How much Quran should we recite in Tahajjud? 10, 100, 1000 verses? In the following hadith from Prophet Muhammad (PBUH) we learn what he said about it.
Prophet Muhammad (PBUH) said: “If anyone prays at night reciting regularly ten verses, he will not be recorded among the negligent; if anyone prays at night and recites one hundred verses, he will be recorded as those who are obedient to Allah; and if anyone prays at night reciting one thousand verses, he will be recorded among those who receive huge rewards.”
Try and pray Tahajjud when you can because you will reap huge rewards from it.
