When do Fajr and Esha times start and end?

“According to the Mufta-Bihi view that is practiced upon in the Hanafi Madhab, when the Shafi’ee Asr time sets in, the time of Zuhr is still remaining; therefore in principle yes, the Zuhr Salaah will be valid if a Hanafi delays it and performs it after the Shafi’ee Asr time has set in.”

“If one completed the salaah before the sun begins to rise, the salaah will be valid. However, if the sun begins to rise while one is performing the fard of fajr salaah, the salaah will break. Later on at the time of ishraaq the salaah will have to be repeated.”

“In principle, if Asr Salaah is performed at Mithl Awwal (Shafi’i/Sahibayn time), the Salaah will be valid, and there will be no need to repeat it. In the inquired scenario, there is room for the permissibility of performing Asr at that time.”

“Yes, one is permitted to perform the pre-Sunnah of Fajr and Zuhr later on the same day they were missed. As for the Sunan of Fajr Salaah, one may perform them between after sunrise (Ishraaq) and before Zawaal. One cannot perform the said Sunan after the Fardh of Fajr before sunrise.”
