Well, we all know that salat must be performed within the waqt (specified time span).
Now I heard once that if 1 rak'ah of the obligatory fazr salah (2 rak'ah) is performed within the waqt, that is, before the sunrise, then the whole 2 rak'ah will be counted as being performed within the waqt.
Is this true and are there any sources supporting this claim?
If there's any problem in my question please inform me. Thanks!
