Praying the Duha prayer is like charity given on behalf of your body

from the Prophet ﷺ that he said: "Each morning, charity is due upon every joint of one of you. Every glorification (saying ‘subḥān Allāh’) is charity, every praise (saying ‘al-ḥamdu lillāh’) is charity, every declaration of Allah’s oneness (saying ‘lā ilāha illā Allāh’) is charity, every magnification (saying ‘Allāhu akbar’) is charity; enjoining what is right is charity and forbidding what is wrong is charity. And two rak'ahs of prayer that one performs at the time of ḍuḥā (forenoon) suffice for all of that."

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ: «يُصْبِحُ عَلَى كُلِّ سُلاَمَى مِنْ أَحَدِكُمْ صَدَقَةٌ، فَكُلُّ تَسْبِيحَةٍ صَدَقَةٌ، وَكُلُّ تَحْمِيدَةٍ صَدَقَةٌ، وَكُلُّ تَهْلِيلَةٍ صَدَقَةٌ، وَكُلُّ تَكْبِيرَةٍ صَدَقَةٌ، وَأَمْرٌ بِالْمَعْرُوفِ صَدَقَةٌ، وَنَهْىٌ عَنِ الْمُنْكَرِ صَدَقَةٌ، وَيُجْزِئُ مِنْ ذَلِكَ رَكْعَتَانِ يَرْكَعُهُمَا مِنَ الضُّحَى۔»

While we were present with Abu Dharr, he said: In the morning, alms are due for him, ever fast is alms, every pilgrimage is alms, every utterance of "Glory to be Allah" is alms, every utterance of "Allah is most great" is alms, every utterance of "Praise be to Allah" is alms. The Messenger of Allah ﷺ recounted all such good works. He then said: Two rak'ahs which one prays in the Duha serve instead of that.

يُصْبِحُ عَلَى كُلِّ سُلاَمَى مِنْ أَحَدِكُمْ فِي كُلِّ يَوْمٍ صَدَقَةٌ فَلَهُ بِكُلِّ صَلاَةٍ صَدَقَةٌ وَصِيَامٍ صَدَقَةٌ وَحَجٍّ صَدَقَةٌ وَتَسْبِيحٍ صَدَقَةٌ وَتَكْبِيرٍ صَدَقَةٌ وَتَحْمِيدٍ صَدَقَةٌ فَعَدَّ رَسُولُ اللَّهِ ﷺ مِنْ هَذِهِ الأَعْمَالِ الصَّالِحَةِ ثُمَّ قَالَ يُجْزِئُ أَحَدَكُمْ مِنْ ذَلِكَ رَكْعَتَا الضُّحَى

The Prophet ﷺ said: In the morning alms are due from every bone in man's fingers and toes. Salutation to everyone he meets is alms; enjoining good is alms; forbidding what is disreputable is alms; removing what is harmful from the road is alms; having sexual intercourse with his wife is alms. The people asked: He fulfils his desire, Messenger of Allah; is it alms? He replied: Tell me if he fulfilled his desire where he had no right, would he commit a sin ? He then said: Two rak'ahs which one prays in the forenoon serve instead of all that. Abu Dawud said: Hammad did not mention enjoining good and forbidding what is disreputable.

عَنِ النَّبِيِّ ﷺ قَالَ يُصْبِحُ عَلَى كُلِّ سُلاَمَى مِنِ ابْنِ آدَمَ صَدَقَةٌ تَسْلِيمُهُ عَلَى مَنْ لَقِيَ صَدَقَةٌ وَأَمْرُهُ بِالْمَعْرُوفِ صَدَقَةٌ وَنَهْيُهُ عَنِ الْمُنْكَرِ صَدَقَةٌ وَإِمَاطَتُهُ الأَذَى عَنِ الطَّرِيقِ صَدَقَةٌ وَبُضْعَتُهُ أَهْلَهُ صَدَقَةٌ قَالُوا يَا رَسُولَ اللَّهِ يَأْتِي شَهْوَتَهُ وَتَكُونُ لَهُ صَدَقَةٌ قَالَ أَرَأَيْتَ لَوْ وَضَعَهَا فِي غَيْرِ حَقِّهَا أَكَانَ يَأْثَمُ قَالَ وَيُجْزِئُ مِنْ ذَلِكَ كُلِّهِ رَكْعَتَانِ مِنَ الضُّحَى

[AI] On the authority of the Prophet ﷺ , he said: "Every joint of a person is obligated to perform charity every day the sun rises. Administering justice between two people is considered charity. Assisting a man to mount his animal or lifting up his belongings onto it is considered charity. A good word is considered charity. Every step taken on the path to performing good deeds is considered charity. Removing harm from the road is considered charity."

Note: There are some missing parts in the original passage that were not preserved.

عَنِ النَّبِيِّ ﷺ قَالَ عَلَى كُلِّ سُلَامَى مِنَ ابْنِ آدَمَ صَدَقَةٌ حِينَ يُصْبِحُ فَشَقَّ ذَلِكَ عَلَى الْمُسْلِمِينَ فَقَالَ رَسُولُ اللهِ ﷺ إِنَّ سَلَامَكَ عَلَى عِبَادِ اللهِصَدَقَةٌ وَإِمَاطَتَكَ الْأَذَى عَنِ الطَّرِيقِ صَدَقَةٌ وَإِنَّ أَمْرَكَ بِالْمَعْرُوفِ صَدَقَةٌ وَإِنَّ نَهْيَكَ عَنِ الْمُنْكَرِ صَدَقَةٌ وَحَدَّثَ أَشْيَاءَ مِنْ نَحْوِ هَذَا لَمْ أَحْفَظْهَا

[AI] The Messenger of Allah ﷺ said, "Every morning, charity is due on every joint of any one of you. Every utterance of praise is charity, every utterance of glorification is charity, every utterance of declaration of the greatness of Allah is charity, every utterance of praise of Allah is charity, commanding good is charity, and forbidding evil is charity. And there is a reward for prayer of two units (rak'at) that one performs during the forenoon (Duha) prayer."

قَالَ رَسُولُ اللهِ ﷺ يُصْبِحُ عَلَى كُلِّ سُلَامَى مِنْ أَحَدِكُمْ صَدَقَةٌ وَكُلُّ تَسْبِيحَةٍ صَدَقَةٌ وَتَهْلِيلَةٍ صَدَقَةٌ وَتَكْبِيرَةٍصَدَقَةٌ وَتَحْمِيدَةٍ صَدَقَةٌ وَأَمْرٌ بِالْمَعْرُوفِ صَدَقَةٌ وَنَهْيٌ عَنِ الْمُنْكَرِ صَدَقَةٌ وَيُجْزِئُ أَحَدَكُمْ مِنْ ذَلِكَ كُلِّهِ رَكْعَتَانِ يَرْكَعُهُمَا مِنَ الضُّحَى

[AI] On the authority of the Prophet ﷺ, he said: "Everyday, every joint of a person has charity. Then he said: 'Being just in your judgment is charity. Removing harmful things from the path is charity. Guiding a person from a place of confusion is charity. Guiding a blind person is charity. Removing a harmful thing from the road is charity. Giving water to the thirsty is charity.' They said: 'O Messenger of Allah, if someone fulfills his sexual desire, will he have a reward?' He said: 'Do you see that if he were to fulfill it illegally, would it be sinful for him?' They said: 'Yes.' He said: 'Likewise, if he fulfills it lawfully, he will have a reward.' Then he mentioned acts of charity continuously. He said: 'And two units of Duha (forenoon) prayer compensate for all of this.'"

عَنِ النَّبِيِّ ﷺ قَالَ يُصْبِحُ كُلَّ يَوْمٍ عَلَى كُلِّ سُلَامَى مِنَ ابْنِ آدَمَ صَدَقَةٌ ثُمَّ قَالَ إِمَاطَتُكَ الْأَذَى عَنِ الطَّرِيقِ صَدَقَةٌ وَتَسْلِيمُكَ عَلَى النَّاسِ صَدَقَةٌ وَأَمْرُكَ بِالْمَعْرُوفِ صَدَقَةٌ وَنَهْيُكَ عَنِ الْمُنْكَرِ صَدَقَةٌ وَمُبَاضَعَتُكَ أَهْلَكَ صَدَقَةٌ قَالَ قُلْنَا يَا رَسُولَ اللهِ أَيَقْضِي الرَّجُلُ شَهْوَتَهُ وَتَكُونُ لَهُ صَدَقَةٌ؟ قَالَ نَعَمْ أَرَأَيْتَ لَوْ جَعَلَ تِلْكَ الشَّهْوَةَ فِيمَا حَرَّمَ اللهُ عَلَيْهِ أَلَمْ يَكُنْ عَلَيْهِ وِزْرٌ؟ قُلْنَا بَلَى قَالَ فَإِنَّهُ إِذَا جَعَلَهَا فِيمَا أَحَلَّ اللهُ فَهِيَ صَدَقَةٌ قَالَ وَذَكَرَ أَشْيَاءَ صَدَقَةً صَدَقَةً قَالَ ثُمَّ قَالَ وَيُجْزِئُ مِنْ هَذَا كُلِّهِ رَكْعَتَا الضُّحَى

[AI] On the authority of the Prophet Muhammad ﷺ , he said, "Every joint of a person has to perform a charity every day that the sun rises: to act justly between two people is a charity; to help a man with his horse, lifting him onto it or hoisting up his belongings onto it, is a charity; a good word is a charity; every step you take towards prayer is a charity; and removing harmful things from the road is a charity." They said, "O Messenger of Allah, is it enough for one of us to satisfy his sexual desire and thereby acquire a reward?" He replied: "Do you know if he were to devote it to something forbidden, would he not be sinning? Likewise, if he were to devote it to something lawful, he would be rewarded." He also mentioned several other acts of charity and then said, "Two units of prayer in the forenoon will suffice for all of that."

عَنِ النَّبِيِّ ﷺ قَالَ «يُصْبِحُ عَلَى كُلِّ سُلَامَى مِنَ ابْنِ آدَمَ كُلَّ يَوْمٍ صَدَقَةٌ» ثُمَّ قَالَ «إِمَاطَتُكَ الْأَذَى عَنِ الطَّرِيقِ صَدَقَةٌ وَتَسْلِيمُكَ عَلَى النَّاسِ صَدَقَةٌ وَأَمْرُكَ بِالْمَعْرُوفِ صَدَقَةٌ وَنَهْيُكَ عَنِ الْمُنْكَرِ صَدَقَةٌ وَمُبَاضَعَتُكَ أَهْلَكَ صَدَقَةٌ» قُلْنَا يَا رَسُولَ اللهِ أَيَقْضِي الرَّجُلُ شَهْوَتَهُ وَتَكُونُ لَهُ صَدَقَةٌ؟ قَالَ «نَعَمْ أَرَأَيْتَ لَوْ جَعَلَ تِلْكَ الشَّهْوَةَ فِيمَا حَرَّمَ اللهُ عَلَيْهِ أَلَمْ يَكُنْ عَلَيْهِ وِزْرًا؟» قُلْنَا بَلَى قَالَ «فَإِنَّهُ إِذَا جَعَلَهَا فِيمَا أَحَلَّ اللهُ لَهُ فَهِيَ صَدَقَةٌ» قَالَ وَذَكَرَ أَشْيَاءَ صَدَقَةً ثُمَّ قَالَ «يُجْزِئُ مِنْ ذَلِكَ كُلِّهِ رَكْعَتَا الضُّحَى»

In the morning charity is due from every bone in the body of every one of you. Every utterance of Allah's glorification is an act of charity. Every utterance of praise of Him is an act of charity, every utterance of profession of His Oneness is an act of charity, every utterance of profession of His Greatness is an act of charity, enjoining good is an act of charity, forbidding what is distreputable is an act of charity, and two rak'ahs which one prays in the forenoon will suffice. (Using translation from Muslim 720)
