Arabic hadith text
حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ زِيَادِ بْنِ عِلاَقَةَ، سَمِعَ الْمُغِيرَةَ، يَقُولُ قَامَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ حَتَّى تَوَرَّمَتْ قَدَمَاهُ ‏.‏ فَقِيلَ يَا رَسُولَ اللَّهِ قَدْ غَفَرَ اللَّهُ لَكَ مَا تَقَدَّمَ مِنْ ذَنْبِكَ وَمَا تَأَخَّرَ ‏.‏ قَالَ ‏"‏ أَفَلاَ أَكُونُ عَبْدًا شَكُورًا ‏"
