Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Whoever offers the dawn prayer, and then his protection is harmed, then the sanctuary of Allah Almighty has been violated and His protection has been breached, and I will demand an account for his protection."
Abu Ya'la recorded it; its chain contains Yazid al-Raqashi, who is da'if (weak), though he has also been declared thiqah (trustworthy).
