[Machine] Regarding the Prophet's ﷺ night prayer, she (Aisha) asked him, "Don't you read this Surah: 'O you wrapped in garments'?". He replied, "Yes". She said, "Verily, Allah, the Mighty and Sublime, made the night prayer obligatory in the beginning of this Surah. The Messenger of Allah ﷺ and his Companions would stand in prayer (at night) for so long that their feet would become swollen. Allah, the Mighty and Sublime, then withheld the last portion for twelve months in the heavens, before revealing it in the Quran. Then Allah, the Mighty and Sublime, revealed the lighter (ruling) at the end of this Surah. So the night prayer became voluntary after the obligatory prayer."
عَنْ قِيَامِ رَسُولِ اللَّهِ ﷺ قَالَتْ أَلَسْتَ تَقْرَأُ هَذِهِ السُّورَةَ {يَا أَيُّهَا الْمُزَّمِّلُ} ؟ قُلْتُ بَلَى قَالَتْ «فَإِنَّ اللَّهَ جَلَّ وَعَلَا افْتَرَضَ الْقِيَامَ فِي أَوَّلِ هَذِهِ السُّورَةِ فَقَامَ نَبِيُّ اللَّهِ ﷺ وَأَصْحَابُهُ حَوْلًا حَتَّى انْتَفَخَتْ أَقْدَامُهُمْ وَأَمْسَكَ اللَّهُ خَاتِمَتَهَا اثْنَيْ عَشَرَ شَهْرًا فِي السَّمَاءِ ثُمَّ أَنْزَلَ اللَّهُ جَلَّ وَعَلَا التَّخْفِيفَ فِي آخِرِ هَذِهِ السُّورَةِ فَصَارَ قِيَامُ اللَّيْلِ تَطَوُّعًا بَعْدَ فَرِيضَتِهِ»
