Sayyiduna Abu Hurayrah (may Allah be pleased with him), while relating his stories, used to say: Your brother (that is, Sayyiduna Abdullah bin Rawahah (may Allah be pleased with him)) used to compose poetry, or speech, that contained no obscenity. He would say: "Among us is the Messenger of Allah, reciting His Book, when the familiar light of dawn breaks forth, shining. He showed us guidance after blindness, so our hearts are certain of it, that it is the truth that will come to pass. He spends the night keeping his side away from his bed, when the beds have grown heavy with the disbelievers."
