حَدَّثَنَا إِسْمَاعِيل بْنُ مُوسَى الْكُوفِيُّ، حَدَّثَنَا دَاوُدُ بْنُ الزِّبْرِقَانِ، عَنْ مَطَرٍ الْوَرَّاقِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ:‏‏‏‏ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ذَاتَ يَوْمٍ لِأَصْحَابِهِ:‏‏‏‏ 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 اللَّهَ غَفَرَ لَهُ . قَالَ أَبُو عِيسَى:‏‏‏‏ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ.

Ibn `Umar narrated that one day, : The Messenger of Allah (ﷺ) 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.”
