[Machine] The Prophet ﷺ used to pray until his feet swelled. He was asked about it and was told that Allah had forgiven his past and future sins. He replied, "Should I not be a grateful servant?"
أَنَّ النَّبِيَّ ﷺ كَانَ يُصَلِّي حَتَّى تَرِمَ قَدَمَاهُ فَقِيلَ لَهُ فِي ذَلِكَ أَتَفْعَلُ وَقَدْ غَفَرَ اللهُ لَكَ مَا تَقَدَّمَ مِنْ ذَنْبِكَِ وَمَا تَأَخَّرَ؟ قَالَ «أَفَلَا أَكُونُ عَبْدًا شَكُورًا؟»
