Umm Hani bint Abi Talib narrated that on the day of the conquest of Mecca, the Prophet (peace and blessings of Allah be upon him) bathed in her house and prayed eight rak'ahs. It is agreed upon (24). From Ali (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) used to perform voluntary prayers during travel. It was narrated by Sa'id (25). One may pray the two rak'ahs of Fajr and the Witr, because Ibn Umar narrated that the Prophet (peace and blessings of Allah be upon him) used to perform the Witr [prayer] while on his camel. And when the Prophet (peace and blessings of Allah be upon him) slept through the Fajr prayer until the sun rose, he prayed the two rak'ahs of Fajr before it. It is agreed upon (26). As for other sunnah prayers and voluntary prayers before and after the obligatory ones, Ahmad said: "I hope that there is no harm in performing voluntary prayers while traveling." It was narrated from Al-Hasan, who said: "The companions of the Messenger of Allah (peace and blessings of Allah be upon him) used to travel and perform voluntary prayers before and after the prescribed prayers" (27). This was also narrated from Umar, Ali, Ibn Mas'ud, Jabir, Anas, Ibn Abbas, Abu Dharr, and many of the Tabi'in. This is the position of Malik, Al-Shafi'i, Ishaq, Abu Thawr, and Ibn al-Mundhir. Ibn Umar, however, would not perform voluntary prayers along with the obligatory prayer, neither before nor after it, except during the middle of the night. This was also reported from Sa'id ibn al-Musayyib, Sa'id ibn Jubayr, and Ali ibn al-Husayn; for it was narrated that Ibn Umar saw people performing voluntary prayers after the prayer, and he said: "If I were to perform voluntary prayers, I would have completed my prayer."
