Not waking up for fajr Salaah
Q: It was narrated that Abu Sa’eed al-Khudri (may Allaah be pleased with him) said: A woman came to the Prophet (peace and blessings of Allaah be upon him) when we were with him and said: “O Messenger of Allaah, my husband Safwaan ibn al-Mu’attal does not pray Fajr until the sun has risen.” Safwaan was with him, so he asked him about what she had said, and he said: “O Messenger of Allaah, we are a family who are known not to wake up until the sun has risen.” He said: “When you wake up, then pray.” Narrated by Abu Dawood, 2459; classed as saheeh by Shaykh al-Albaani in Irwa’ al-Ghaleel, 7/65.
I can't pray fajr salah because I have sleep problems. I don't fall asleep easily and if I wake up for fajr I can't fall asleep again so can I pray fajr at zuhr time, would it be valid and am I a kafir if I don't pray fajr on time. Above hadith it says our prophet allowed a man to pray fajr after sunrise.
