Sunan at-Tirmithiy كتاب الدعوات باب [ من قال سبحان الله غرست له نخلة فى الجنة ]

حَدَّثَنَا نَصْرُ بْنُ عَبْدِ الرَّحْمَنِ الْكُوفِىُّ حَدَّثَنَا الْمُحَارِبِىُّ عَنْ مَالِكِ بْنِ أَنَسٍ عَنْ سُمَىٍّ عَنْ أَبِى صَالِحٍ عَنْ أَبِى هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ مَنْ قَالَ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ مِائَةَ مَرَّةٍ غُفِرَتْ لَهُ ذُنُوبُهُ وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ. قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ.
The Messenger of God, peace and blessings of God be upon him, said, "Whoever says, 'Exalted is God with all praise due to Him' one hundred times, [in a day (1)] has his (2) sins forgiven, even if they were as abundant as sea foam."
(1) This can be in one sitting or throughout the day in several sittings. (2) Masculine pronouns are generally used in Arabic as a means for referring to both men and women when the meaning is left general and is not otherwise specified.
