Arabic (Original)
حَدَّثَنَا سُفْيَانُ عَنْ زِيَادِ بْنِ عِلَاقَةَ سَمِعَ الْمُغِيرَةَ بْنَ شُعْبَةَ قَالَ قَامَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حَتَّى تَوَرَّمَتْ قَدَمَاهُ فَقِيلَ لَهُ يَا رَسُولَ اللَّهِ قَدْ غَفَرَ اللَّهُ لَكَ مَا تَقَدَّمَ مِنْ ذَنْبِكَ فَقَالَ أَوَلَا أَكُونُ عَبْدًا شَكُورًا.
English Translation
Sufyan told us, from Ziyad ibn Ilaqah: he heard al-Mughirah ibn Shu'bah say: The Messenger of God, peace and blessings be upon him, stood in prayer until his feet swelled, and it was said to him, "O Messenger of God, God has already forgiven you your past sins," and he said, "Should I not then be a grateful servant?"
