Mujahid narrates from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that a man said to him: Should I pray behind the imam in Ramadan? Ibn Umar (may Allah be pleased with them both) said: Are you not a hafiz (of the Qur'an)? He said: Yes! I am a hafiz. Ibn Umar (may Allah be pleased with them both) said: Will you stay silent like a donkey? Pray in your house.
