Wiping over socks: Abu Hanifah disliked wiping over socks and sandals unless their soles are leather

Al-Mukhdaji, a man of Banu Kinanah, states that there was a man of the Ansar in al-Sham who had the honour of companionship and whose kunyah was Abu Muhammad. He stated that witr is obligatory (wajib). Al-Mukhdaji mentions that he went to Sayyiduna Ubadah bin al-Samit (may Allah be pleased with him) and told him this (that witr is obligatory). Sayyiduna Ubadah said: "Abu Muhammad has said something wrong. I heard the Prophet (peace and blessings be upon him) say: 'There are five prayers which Allah Almighty has made obligatory upon His servants. Whoever performs them (brings them) without having neglected anything of their rights will come in such a state that he has a covenant with Allah Almighty that He will admit him to Paradise. And whoever falls short in any of their rights will come in such a state that he has no covenant with Allah Almighty. If Allah wills, He will punish him, and if Allah wills, He will admit him to Paradise.'"

Muslim, the freedman of Abd al-Qays, states that a man said to Sayyiduna Ibn Umar (may Allah be pleased with them both): "What is your view: is witr a sunnah?" He said: "What is 'sunnah'? The Prophet (peace and blessings be upon him) performed witr and the Muslims performed witr (that is all)." The questioner said: "No. Is it a sunnah?" He said: "Leave it! Do you have any sense? The Prophet (peace and blessings be upon him) performed witr and the Muslims performed witr. (That is the end of the matter.)"

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that it was said to him: "Is witr obligatory?" He said: "The Prophet (peace and blessings be upon him) performed witr, and the Muslims have remained steadfast upon it."

Asim bin Damrah said that Sayyiduna Ali al-Murtada (may Allah be pleased with him) said: "Witr is not binding like the obligatory prayers."

Sa'id bin al-Musayyib said: The Prophet (peace and blessings be upon him) established witr as a sunnah just as he (peace and blessings be upon him) established the charity of Fitr and the sacrifice as a sunnah.

Mujahid states that witr is a sunnah.

It is narrated about al-Sha'bi that he was asked about a man who forgot (to perform) witr. He said: "This does not harm him. As though it were obligatory?"

It is narrated about al-Hasan that he did not consider witr to be obligatory.

Ata and Muhammad bin Ali both said that the sacrifice and witr are a sunnah. And it is mentioned that the view of (Imam) Abu Hanifah is: witr is obligatory.
