Night prayer in Ramadan

Sayyidah Aishah Siddiqah (may Allah be pleased with her) narrates this saying of the Prophet (peace and blessings be upon him): "Whoever stands (in prayer) in Ramadan with faith and hoping for reward, his past sins are forgiven."
Al-Bazzar recorded it. Its chain contains a narrator, Ibrahim bin Isma'il bin Mujammi', and he is da'if (weak).

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) encouraging the night prayer in Ramadan; however, the Prophet (peace and blessings be upon him) did not gather (the people) for the night prayer in Ramadan. (Allamah al-Haythami says:) I say: This part of it is narrated in the Sahih: "The Prophet (peace and blessings be upon him) used to encourage the night prayer in Ramadan."
Ahmad recorded it, and its chain is hasan (good).

Sayyiduna Abu Dharr al-Ghifari (may Allah be pleased with him) narrates: I said to the Prophet (peace and blessings be upon him): "I would like to spend tonight with you and pray following your prayer." The Prophet (peace and blessings be upon him) said: "You will not be able to." Then the Prophet (peace and blessings be upon him) got up and performed the ritual bath (ghusl). A screen was made for him with a cloth, and I turned my face away from him while he bathed. Then I did the same. Then the Prophet (peace and blessings be upon him) stood up to pray, and I stood with him, until, because of the length of his prayer, I began striking my head against the wall. Then Sayyiduna Bilal (may Allah be pleased with him) came to call him to the prayer. The Prophet (peace and blessings be upon him) asked: "Have you done it?" He said: "Yes." The Prophet (peace and blessings be upon him) said: "O Bilal! You give the call to prayer (adhan) when the dawn is still spread lengthwise up the sky, and that is not the true dawn; the true dawn spreads like this, across the breadth (of the horizon)." Then the Prophet (peace and blessings be upon him) called for his pre-dawn meal and ate suhur.
Ahmad recorded it, and its chain contains a narrator, Rishdin bin Sa'd, about whom there has been much criticism, though he has also been declared trustworthy.

Zayd bin Wahb narrates: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) used to lead us in prayer in the month of Ramadan, and we would finish the prayer and leave while it was still night.
Al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are the narrators of the Sahih.

Sayyiduna Jabir (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) led us in eight rak'ahs in the month of Ramadan and prayed the witr. When the next night came, we gathered in the mosque, hoping that he would come out to us, but he remained (in his house) until morning came. Then we went in to him and said: "O Messenger of Allah! We had gathered in the mosque, hoping that you would lead us in prayer." The Prophet (peace and blessings be upon him) said: "I feared (the narrator is unsure; perhaps the words are:) I disliked that it should be made obligatory upon you."
Abu Ya'la and al-Tabarani in al-Mu'jam al-Saghir recorded it. Its chain contains a narrator, Isa bin Jariyah, whom Ibn Hibban and others declared thiqah (trustworthy), while Yahya bin Ma'in declared him da'if (weak).

Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) used to pray at night in Ramadan. Some people came and prayed, and the Prophet (peace and blessings be upon him) kept the prayer short. Then he went into his house and prayed alone, then came out and again led a short prayer. The next morning the people said: "O Messenger of Allah! We prayed behind you last night; you went into your house and then came out again." He said: "I did that for your sake."
Al-Tabarani recorded it in al-Mu'jam al-Awsat, and its narrators are the narrators of the Sahih.
