(2) باب الصَّلاَةِ مَعَ أَئِمَّةِ الْجَوْرِ
It was narrated that 'Abdullih said:
"The Messenger of Allah (ﷺ) said: 'You may live to meet people who will be offering the prayer outside its (prayer) time. If you meet them, then offer the prayer on time, then pray with them and make that a voluntary prayer."'
