Musannaf Ibn Abi Shaybah 3258 — All the prayer times

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) was asked about the Fajr prayer. He ordered Sayyiduna Bilal (may Allah be pleased with him) to call the adhan when dawn broke, and then on the next day to call the adhan when it had become light. Then he said: "Where is the one who asked? The time of Fajr is between these two times."

Abu Qilabah (may Allah have mercy on him) narrates that a man came to Sayyiduna Abu Bakr (may Allah be pleased with him) and said: "I saw in a dream that I was urinating blood." He said: "I think you go to your wife while she is menstruating." He said: "Yes." He said: "Then fear Allah and do not do it again."
