Delaying the Salaah till the last time
Q:
1. I prayed Fajr at about 6:02 and it expires on the calendar at about 6:06, but before I prayed I looked outside and at first I noticed it was light and at the distance I seen in the clouds a reddish smudge, like at the time of Maghrib. Can Fajr expire before the calendar time or is it 100% accurate?
2. I prayed Fajr Qada in-case and at my last rak'ah in tashahhud I didn't have khushoo as I needed to relieve myself, does this affect the validity of my prayer? I leant on one side to hold it and before tasleem I moved back.
