Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) and Sayyiduna Abu Hurairah (may Allah be pleased with him) narrate that the Prophet Muhammad (peace and blessings be upon him) said: "Whoever wakes up at night and wakes up his wife, and both of them stand and perform two rak'ahs, then both of their names are written among the men who remember Allah much and the women who remember Allah much."
