Sayyiduna Qais bin Qahd (may Allah be pleased with him) narrates: He performed the morning prayer behind the Prophet Muhammad (peace be upon him). He had not been able to perform the two rak'ahs of Sunnah before Fajr. When the Prophet (peace be upon him) finished the prayer with salam, he stood up and performed the two rak'ahs of Sunnah for Fajr. The Prophet (peace be upon him) kept looking at him, but did not object to him.
