Mishkat al-Masabih 4 Prayer كتاب الصلاة 655

وَعَنِ ابْنِ عُمَرَ أَنَّ أَبَاهُ عُمَرَ بْنَ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ كَانَ يُصَلِّي مِنَ اللَّيْلِ مَا شَاءَ اللَّهُ حَتَّى إِذَا كَانَ مِنْ آخِرِ اللَّيْلِ أَيْقَظَ أَهْلَهُ لِلصَّلَاةِ يَقُولُ لَهُمْ: الصَّلَاةُ ثُمَّ يَتْلُو هَذِهِ الْآيَةَ: (وَأْمُرْ أَهْلَكَ بِالصَّلَاةِ وَاصْطَبِرْ عَلَيْهَا لَا نَسْأَلُكَ رِزْقًا نَحن نرزقك وَالْعَاقبَة للتقوى) رَوَاهُ مَالك

Ibn ‘Umar said that his father ‘Umar b. al-Khattab used to pray during the night what God wished, then during the latter part of the night he woke his family for prayer saying to them, “Come to prayer.” Then he would recite this verse, “And command your family to observe the prayer, and be constant in it. We do not ask you for provision; We provide you, and the issue pertains to piety” (Al-Qur’an; 20:132). Malik transmitted it.
