Those who ordered praying at night

It is narrated from al-Hasan that the Messenger of Allah (peace and blessings be upon him) said: "Pray four rak'ahs at night; pray it even if only two rak'ahs. For whichever household makes the night prayer (tahajjud) its habit, a caller calls out: 'O people of the house, get up for your prayer!'"

It is narrated from al-Hasan that the Messenger of Allah (peace and blessings be upon him) said: "May Allah Almighty have mercy on a man who prays the night prayer (tahajjud), then wakes his wife and she prays the night prayer. May Allah Almighty have mercy on a woman who prays the night prayer, then wakes her husband and he prays the night prayer."

Al-Hasan said: Pray the night prayer (tahajjud), even if it is only for as long as it takes to milk a goat.

Muhammad considered it recommended that a man should not abandon the night prayer (tahajjud), even if it is only for as long as it takes to milk a goat.

Sayyiduna Abdullah (may Allah be pleased with him) said: The reward of the night prayer exceeds that of the day prayer as much as the reward of giving charity in secret exceeds that of giving charity openly.

The grandmother of al-Zubayr bin Abdullah bin Ruhaymah said: Sayyiduna Uthman (may Allah be pleased with him) used to fast continually and stand in prayer at night, except that he would lie down briefly in the first part of the night.

Sayyiduna Abdullah (may Allah be pleased with him) said: A man was mentioned in the presence of the Prophet (peace and blessings be upon him): that he slept through the night until morning. The Prophet (peace and blessings be upon him) said: "Satan urinated in his ears."

Sayyiduna Abu Hurayrah and Sayyiduna Abu Sa'id (may Allah be pleased with them both) said: When a man wakes his wife at night and they both pray the night prayer (tahajjud), they are both recorded among the men who remember Allah much and the women who remember Him.
