سُنَنُ ابْنِ مَاجَهْ
Sunan Ibn Majah 226
The Book of the Sunnah
The virtue of the scholars, and encouragement to seek knowledge
حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَنْبَأَنَا مَعْمَرٌ، عَنْ عَاصِمِ بْنِ أَبِي النَّجُودِ، عَنْ زِرِّ بْنِ حُبَيْشٍ، قَالَ أَتَيْتُ صَفْوَانَ بْنَ عَسَّالٍ الْمُرَادِيَّ فَقَالَ مَا جَاءَ بِكَ قُلْتُ أُنْبِطُ الْعِلْمَ . قَالَ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ مَا مِنْ خَارِجٍ خَرَجَ مِنْ بَيْتِهِ فِي طَلَبِ الْعِلْمِ إِلاَّ وَضَعَتْ لَهُ الْمَلاَئِكَةُ أَجْنِحَتَهَا رِضًا بِمَا يَصْنَعُ .
It was narrated that Zirr bin Hubaish said: "I went to Safwan bin 'Assal Al-Muradi and he said: 'What brought you here?' I said: 'I am seeking knowledge.' He said: 'I heard the Messenger of Allah say: "There is no one who goes out of his house in order to seek knowledge, but the angels lower their wings in approval of his action.'"
