Abu al-Tufayl (may Allah have mercy on him) relates: I saw the Commander of the Believers, Sayyiduna Ali bin Abi Talib (may Allah be pleased with him), standing on the pulpit, and he said: "Ask me (whatever you wish to ask) before you are unable to ask me, for after me you will not find anyone like me (in knowledge) to address you." So Ibn al-Kawwa' stood up and said: "O Commander of the Believers, what is meant by 'those scattering (dust) dispersing'?" He said: "The winds." He asked: "What are 'those carrying a load'?" He said: "The clouds." He asked: "What is meant by 'those sailing with ease'?" He said: "The ships." He asked: "Who are 'those apportioning by command'?" He said: "The angels." He asked: "Who are 'those who exchanged the favour of Allah for disbelief and settled their people in the home of ruin' [Surah Ibrahim: 28] ?" He said: "They are the hypocrites of Quraysh." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
