Sayyidah Aishah (may Allah be pleased with her) said: "If the Messenger of Allah (peace and blessings be upon him) had concealed anything of the Book of Allah, he would have concealed this verse: 'And when you said to the one on whom Allah had bestowed favour and on whom you had bestowed favour'" up to His words: 'We married her to you.' [Surah al-Ahzab: 37]
