The Prophet ﷺ as saying: In the morning alms are due for every bone in man's body. His salutation to everyone he meets is alms, his enjoining good is alms, his forbidding what is evil is alms, the removal of harmful thing from the way is alms, to have sexual intercourse with one's wife if alms, and two rak'ahs which one prays in the Duha serve instead of that. Abu Dawud said: The tradition narrated by 'Abbad is more perfect (than the version narrated by Musaddad). Musaddad did not mention in his version "the command (of good) and the prohibition (of evil)". Instead, he added in his version saying: "Such and such." Ibn Ma'na added in his version: "They (the people) said: Messenger of Allah, how is that one of us fulfills his desire and still there are alms for him (i.e. is rewarded)? He replied: What do you think if you had unlawful sexual intercourse, would he not have been a sinner ?  

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 وَبُضْعَةُ أَهْلِهِ صَدَقَةٌ وَيُجْزِئُ مِنْ ذَلِكَ كُلِّهِ رَكْعَتَانِ مِنَ الضُّحَى  

[Machine] 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  

[Machine] 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»  

"يُصْبحُ عَلَى كُلِّ سُلَامَى مِنْ ابْنِ آدَمَ صَدَقَةٌ، تَسْلِيمُهُ عَلَى مَنْ لَقِى صَدَقَةٌ، وَأَمْرُهُ بِالْمَعْرُوفِ صَدَقَةٌ، وَنَهْيُهُ عَنِ الْمُنْكَرِ صَدَقَةٌ، وَإِمَاطَتُهُ الأَذَى مِنَ الطَّرِيقِ صَدَقَةٌ، وَبُضْعُهُ أَهْلَهُ صَدَقَةٌ، وَيُجْزِئُ مِنْ ذَلِكَ رَكْعَتَانِ مِنَ الضُّحَى، قَالُوا: يَا رَسُولَ اللَّه: أَحَدُنَا يَقْضِى شَهْوَتَهُ وَيَكُونُ لَهُ صَدَقَةٌ؟ قَالَ: أَرَأَيْتَ لَوْ وَضَعَهَا فِي غَيْرِ حِلِّهَا أَلَمْ يَكُنْ يَأثَمُ".
