A similar hadith is also narrated from Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him).
Abdullah bin Ahmad (may Allah have mercy on him) said: Uthman (bin Abi Shaybah) made a mistake in this; this is actually the hadith: "The mu'aqqibat (glorifications said after the prayer), whose sayer is never disappointed."
