Majma al-Zawaid — Hadith 11847

Wahb bin Munabbih narrates: I accompanied Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) both before he lost his sight and after he lost it. He was asked about the decree, and he said: I have found that the boldest of people in speaking about it is the most ignorant of it, and the weakest of them in speaking about it is the most knowledgeable of it. And I have also found that the one who reflects on it is like one who looks at the rays of the sun: the more he looks, the more his sight is bewildered by it.
Al-Tabarani recorded it; its chain contains Yazid bin Abi Salamah, whom Yahya bin Ma'in declared da'if (weak).
