مُحَمَّدُ بْنُ أَحْمَدَ بْنِ يَحْيَى عَنْ إِبْرَاهِيمَ بْنِ هَاشِمٍ عَنْ عَمْرِو بْنِ عُثْمَانَ عَنْ مُحَمَّدِ بْنِ عُذَافِرٍ قَالَ قَالَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ صَلاَةُ اَلتَّطَوُّعِ بِمَنْزِلَةِ اَلْهَدِيَّةِ مَتَى مَا أُتِيَ بِهَا قُبِلَتْ فَقَدِّمْ مِنْهَا مَا شِئْتَ وَأَخِّرْ مِنْهَا مَا شِئْتَ»
Muhammad ibn Ahmad ibn Yahya narrated from Ibrahim ibn Hashim from Amr ibn Uthman from Muhammad ibn Udhafir who said:
Abu Abdillah عليه السلام, peace be upon him, said: "The supererogatory prayer is like a gift, whenever it is offered, it is accepted. So offer from it whatever you wish earlier, and delay from it whatever you wish."
