Q: Can I pray in leggings if my top ends a few inches above my ankles?

Q: Until what time can you read your zuhr salaah?

Q: Is not covering the feet below the ankles for woman against sunnah? I have severe waswasa and I found out that except for Hanafi's, others consider the feet as awrah. Are my prayers invalid as I didn't cover it after knowing about the ruling. Why do Hanafi's not consider the feet as awrah. I feel scared that my namaz isn't valid. What should I do?

Q: Does the area starting from the chin need to be covered during salaah for women?

Q: In my country, it is compulsory to use hand sanitizer before entering any shop for shopping, etc. All of the hand sanitizers have alcohol in it. What is the ruling regarding praying salaah, touching Quraan or eating after using it?

Will her namaaz be valid?

Q: If a person prays while wearing a t-shirt that has depictions of creatures on it, is his prayer valid or should he repeat it?
