Sunan Ibn Majah 4101
“The Messenger of Allah (ﷺ) said: ‘If you see a man who has been given indifference with regard to this world and who speaks little, then draw close to him for he will indeed offer wisdom.’”
" إِذَا رَأَيْتُمُ الرَّجُلَ قَدْ أُعْطِيَ زُهْدًا فِي الدُّنْيَا وَقِلَّةَ مَنْطِقٍ فَاقْتَرِبُوا مِنْهُ فَإِنَّهُ يُلَقَّى الْحِكْمَةَ "
