“The Messenger of Allah ﷺ stood (in prayer) until his feet became swollen. It was said: ‘O Messenger of Allah, Allah has forgiven you your past and future sins.’ He said: ‘Should I not be a thankful slave?’” (Using translation from Ibn Mājah 1419)

قَامَ رَسُولُ اللهِ ﷺ حَتَّى تَوَرَّمَتْ قَدَمَاهُ فَقِيلَ لَهُ يَا رَسُولَ اللهِ قَدْ غَفَرَ اللهُ لَكَ مَا تَقَدَّمَ مِنْ ذَنْبِكَ فَقَالَ أَوَلَا أَكُونُ عَبْدًا شَكُورًا
