Jami` at-Tirmidhi, Book 48, Hadith 101 (In-Book) ⓘ

Ibn `Umar narrated that one day, : The Messenger of Allah said to his Companions: “Say ‘Glory is to Allah and with His Praise (Subḥān Allāh, wa biḥamdih)’ a hundred times. Whoever says [it] one time, it is written for him ten, and whoever says it ten (times), it is written for him a hundred, and whoever says it a hundred (times), it is written for him a thousand, and whoever increases, Allah will increase for him, and whoever seeks Allah’s forgiveness, [Allah] will forgive him.”

حَدَّثَنَا إِسْمَاعِيلُ بْنُ مُوسَى الْكُوفِيُّ، حَدَّثَنَا دَاوُدُ بْنُ الزِّبْرِقَانِ، عَنْ مَطَرٍ الْوَرَّاقِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ذَاتَ يَوْمٍ لأَصْحَابِهِ ‏ "‏ قُولُوا سُبْحَانَ اللَّهِ وَبِحَمْدِهِ مِائَةَ مَرَّةٍ مَنْ قَالَهَا مَرَّةً كُتِبَتْ لَهُ عَشْرًا وَمَنْ قَالَهَا عَشْرًا كُتِبَتْ لَهُ مِائَةً وَمَنْ قَالَهَا مِائَةً كُتِبَتْ لَهُ أَلْفًا وَمَنْ زَادَ زَادَهُ اللَّهُ وَمَنِ اسْتَغْفَرَ غَفَرَ اللَّهُ لَهُ ‏" ‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ ‏.‏
