[Machine] One day, the Messenger of Allah ﷺ passed by me, so I said, "O Messenger of Allah, I have grown old and weak, or as she said. So command me to do a deed while I am sitting." He said, "Say 'Subhan Allah' (Glory be to Allah) one hundred times, as it is equivalent to freeing one hundred slaves from the offspring of Isma'il and say 'Alhamdulillah' (Praise be to Allah) one hundred times, as it is equivalent to riding one hundred armored horses carrying you in the cause of Allah, and say 'Allahu Akbar' (Allah is the Greatest) one hundred times, as it is equivalent to killing one hundred hostile enemies, and say 'La ilaha illallah' (There is no deity except Allah) one hundred times, as it fills the space between the heavens and the earth. On that day, no one brings a deed like yours except if they were to bring the same."
مَرَّ بِي ذَاتَ يَوْمٍ رَسُولُ اللهِ ﷺ فَقُلْتُ يَا رَسُولَ اللهِ إِنِّي قَدْ كَبِرْتُ وَضَعُفْتُ أَوْ كَمَا قَالَتْ فَمُرْنِي بِعَمَلٍ أَعْمَلُهُ وَأَنَا جَالِسَةٌ قَالَ سَبِّحِي اللهَ مِائَةَ تَسْبِيحَةٍ فَإِنَّهَا تَعْدِلُ لَكِ مِائَةَ رَقَبَةٍ تُعْتِقِينَهَا مِنْ وَلَدِ إِسْمَاعِيلَ وَاحْمَدِي اللهَ مِائَةَ تَحْمِيدَةٍ فإنها تَعْدِلُ لَكِ مِائَةَ فَرَسٍ مُسْرَجَةٍ مُلْجَمَةٍ تَحْمِلِينَ عَلَيْهَا فِي سَبِيلِ اللهِ وَكَبِّرِي اللهَ مِائَةَ تَكْبِيرَةٍفَإِنَّهَا تَعْدِلُ لَكِ مِائَةَ بَدَنَةٍ مُقَلَّدَةٍ مُتَقَبَّلَةٍ وَهَلِّلِي اللهَ مِائَةَ تَهْلِيلَةٍ قَالَ ابْنُ خَلَفٍ أَحْسِبُهُ قَالَ تَمْلَأُ مَا بَيْنَ السَّمَاءِ وَالْأَرْضِ وَلَا يُرْفَعُ يَوْمَئِذٍ لِأَحَدٍ مِثْلُ عَمَلِكَ إِلَّا أَنْ يَأْتِيَ بِمِثْلِ مَا أَتَيْتِ بِهِ
