Musnad Abi Ya'la 2665 — from Sayyiduna Ibn Abbas

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both), concerning the words of Allah Almighty, 'gently (rukha'an) wherever he willed (haythu asab),' that he said: "Al-rukha' means the wind that is obedient (to the command)." And concerning the words of Allah Almighty 'haythu asab' he said: "It means the place that he intended." And in the interpretation of the words of Allah Almighty, 'He sends the winds, and they stir up clouds, and He spreads them in the sky however He wills and makes them into fragments (kisafan),' he said: "It means pieces of cloud that lie layer upon layer, one above another." And concerning 'and you see the wadq' he said: "It means rain, which comes out from between the clouds."
