Hazrat Zar bin Hubaysh narrates from Sayyiduna Abu Darda (may Allah be pleased with him) that he said: Whoever intends in his heart to perform prayer at any hour of the night, then sleep overcomes him, his sleep will be a charity for him, and the reward for the prayer will be written for him according to his intention and resolve. Hazrat Abda bin Abi Lubabah mixed up the chain of this hadith. Once, when narrating, he said that he narrates this from Suwaid bin Ghaflah (see narration number 1172), and another time he attributed it to Zar bin Hubaysh (as in narration number 1173). Hazrat Abda was in doubt whether this narration is from Zar or from Suwaid.
