Messenger of Allah you do this (in spite of the fact) that your earlier and later sins have been pardoned for you? Thereupon, he said. A'isha should I not prove myself to be a thanksgiving servant (of Allah)? (Using translation from Muslim 2820)
كَانَ رَسُولُ اللهِ ﷺ إِذَا صَلَّى قَامَ حَتَّى تَفْطُرَ رِجْلَاهُ فَقَالَتْ عَائِشَةُ ؓ يَا رَسُولَ اللهِ تَصْنَعُ هَذَا وَقَدْ غَفَرَ اللهُ لَكَ مَا تَقَدَّمَ مِنْ ذَنْبِكَ وَمَا تَأَخَّرَ؟ قَالَ يَا عَائِشَةُ أَفَلَا أَكُونُ عَبْدًا شَكُورًا؟
