[Machine] The Prophet ﷺ used to pray until his feet would crack. It was said to him, "Hasn't Allah forgiven you for your past and future sins?" He said, "Should I not be a grateful servant?"

كَانَ رَسُولُ اللهِ ﷺ يُصَلِّي حَتَّى تَنْفَطِرَ قَدَمَاهُ فَقِيلَ لَهُ أَلَيْسَ قَدْ غَفَرَ اللهُ لَكَ مَا تَقَدَّمَ مِنْ ذَنْبِكَ وَمَا تَأَخَّرَ؟ قَالَ «أَفَلَا أَكُونُ عَبْدًا شَكُورًا؟»
