[Machine] The Messenger of Allah ﷺ passed by me one day, so I said to him, "Tell me about a deed that I can do while sitting." He said, "Recite one hundred Tasbih (subhan Allah), for it is equivalent to freeing one hundred slaves from the offspring of Isma'il. And recite one hundred Tahmid (alhamdulillah), for it is equivalent to one hundred trained and saddled horses that you carry in the cause of Allah. And say one hundred Takbir (Allahu akbar), for it is equivalent to one hundred acceptable sacrifices. And say one hundred Tahleel (la ilaha illallah), for it fills the space between the heavens and the earth." Abu Khalaf said, "I do not think that it is possible." He (the Prophet) said, "It fills what is between the heavens and the earth."
مَرَّ بِي رَسُولُ اللهِ ﷺ ذَاتَ يَوْمٍ فَقُلْتُ مُرْنِي بِعَمَلٍ أَعْمَلُهُ وَأَنَا جَالِسَةٌ قَالَ «سَبِّحِي اللهَ مِائَةَ تَسْبِيحَةٍ فَإِنَّهَا تَعْدِلُ مِائَةَ رَقَبَةٍ مِنْ وَلَدِ إِسْمَاعِيلَ وَاحْمِدِي اللهَ مِائَةَ تَحْمِيدَةٍ فَإِنَّهَا تَعْدِلُ أَيْ مِائَةَ فَرَسٍ مُسْرَجَةٍ مُلْجَمَةٍ تَحْمِلِينَ عَلَيْهَا فِي سَبِيلِ اللهِ وَكَبِّرِي مِائَةَ تَكْبِيرَةٍ فَإِنَّهَا تَعْدِلُ مِائَةَ بَدَنَةٍ مُقَلَّدَةٍ مُتَقَبَّلَةٍ وَهَلِّلِي اللهَ مِائَةَ تَهْلِيلَةٍ» قَالَ أَبُو خَلَفٍ لَا أَحْسِبُهُ إِلَّا قَالَ «تَمْلَأُ مَا بَيْنَ السَّمَاءِ وَالْأَرْضِ»
