[Machine] I heard the Messenger of Allah ﷺ saying, Allah the Exalted has said: "O son of Adam, do not be incapable of performing four units of prayer at the beginning of the day, as it will suffice you until the end." And it was narrated by Ar-Rabi' ibn Sulaiman ibn Dawud, from Abdullah ibn Yusuf, from Al-Haytham ibn Humeid, from Abu Al-A'la ibn Al-Harith, from Makhooul, from Kathir ibn Murrah.  

الكبرى للنسائي:٤٦٨أَخْبَرَنِي هَارُونُ بْنُ عَبْدِ اللهِ قَالَ حَدَّثَنَا مَعْنٌ قَالَ حَدَّثَنَا مُعَاوِيَةُ بْنُ صَالِحٍ عَنْ أَبِي الزَّاهِرِيَّةِ عَنْ كَثِيرِ بْنِ مُرَّةَ عَنْ نُعَيْمٍ قَالَ

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ قَالَ اللهُ تَعَالَى «ابْنَ آدَمَ لَا تَعْجِزْ عَنْ أَرْبَعِ رَكَعَاتٍ مِنْ أَوَّلِ النَّهَارِ أَكْفِكَ آخِرَهُ» 469 وَعَنِ الرَّبِيعِ بْنِ سُلَيْمَانَ بْنِ دَاوُدَ عَنْ عَبْدِ اللهِ بْنِ يُوسُفَ عَنِ الْهَيْثَمِ بْنِ حُمَيْدٍ عَنْ أَبِي الْعَلَاءِ بْنِ الْحَارِثِ عَنْ مَكْحُولٍ عَنْ كَثِيرِ بْنِ مُرَّةَ بِهِ
