Offering Salah at its due time although the Adhan is not announced on time

Q 1: We offer Salah (Prayer) at its due time although the Adhan (call to Prayer) is not called on time. Is it valid or should we repeat it?

A: The Five Obligatory Daily Prayers have fixed prescribed times on which they should be offered, according to Allah's saying, Verily, As-Salât (the prayer) is enjoined on the believers at fixed hours. This means that it is as proven as the Qur'an and fixed in regular times.The beginning of the time of Salah is a condition for its validity. If a person offers Salah before the beginning of its time, their Salah is Batil (null and void), as they have offered it in a different time other than that prescribed by Allah (Exalted be He). If anything is done in a way other than that prescribed by Allah, it is Batil.If you find out that you used to offer Salah before the beginning of its time, you should repeat it. If it is out of your negligence and carelessness, (Part No. 5; Page No. 86) you should also perform Tawbah (repentance to Allah) and Istighfar (seeking forgiveness from Allah) for what you did, and insist on not doing it again. If it was out of ignorance of the ruling or the time, there is no harm on you, but you should repeat the Salah. It is not one of the conditions of the validity of Salah to pronounce the Adhan after the beginning of its time; it is valid if it is offered in its prescribed time. However, the Mu'adhin (caller to Prayer) should repeat the Adhan, unless there is another person who pronounces the Adhan on its time instead of him.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
