Arabic hadith text
حَدَّثَنَا صَدَقَةُ بْنُ الْفَضْلِ، أَخْبَرَنَا ابْنُ عُيَيْنَةَ، حَدَّثَنَا زِيَادٌ، أَنَّهُ سَمِعَ الْمُغِيرَةَ، يَقُولُ قَامَ النَّبِيُّ صلى الله عليه وسلم حَتَّى تَوَرَّمَتْ قَدَمَاهُ فَقِيلَ لَهُ غَفَرَ اللَّهُ لَكَ مَا تَقَدَّمَ مِنْ ذَنْبِكَ وَمَا تَأَخَّرَ قَالَ " أَفَلاَ أَكُونُ عَبْدًا شَكُورًا ".
Translation
Sadaqa ibn al-Fadl related to us: Ibn Uyayna informed us: Ziyad related to us that he heard al-Mughira say: The Prophet (peace and blessings of Allah be upon him) stood in prayer until his feet swelled. He was told: Allah has forgiven you your past and future sins. He said: 'Should I not be a grateful servant?'
