Hadith 1157
فَقَصَّتْ حَفْصَةُ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِحْدَى رُؤْيَايَ ، فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : نِعْمَ الرَّجُلُ عَبْدُ اللَّهِ لَوْ كَانَ يُصَلِّي مِنَ اللَّيْلِ فَكَانَ عَبْدُ اللَّهِ رَضِيَ اللَّهُ عَنْهُ يُصَلِّي مِنَ اللَّيْلِ .
Hafsa narrated one of my dreams to the Prophet and the Prophet said, "Abdullah is a good man. Would that he offer the night prayer (Tahajjud)!" So after that day `Abdullah (bin `Umar) started offering Tahajjud.
