Prayer is the mainstay of religion, and it is the main pillar of Islam that every Muslim must fulfill without any excuse. The Prophet's comfort was provided through prayer. Therefore, he used to perform a lot of supererogatory prayers, to the extent that he would offer Qiyām al-Layl until his feet would swell due to his prolonged standing before Allah Almighty, reciting, supplicating, showing humility, and imploring Allah. In this Hadīth, the Prophet (may Allah's peace and blessings be upon him) informs us that the best thing regarding prayer, in general, is the long qunūt, which refers to the prolonged standing in prayer for recitation. It is explicitly mentioned in a Hadīth narrated by Abu Dāwūd, in which ‘Abdullāh ibn Habashi al-Khath‘ami (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) was asked: "Which deed is the best?" He said: "The prolonged standing." Qunūt may also refer to supplication, humility, and subservience before Allah Almighty. The Prophet (may Allah's peace and blessings be upon him) used to do that, especially during supererogatory prayers and Qiyām al-Layl. He would pause at every verse and would not go past any verse containing a supplication without supplication with it, or a punishment without seeking the refuge of Allah Almighty from it, and so on. An obligatory prayer - even if it does not include prolonged standing, recitation, and supplication - is better than a supererogatory prayer that contains such prolongation. This is because Allah Almighty ordained the obligatory prayer and fixed a certain time and a number of Rak‘ahs for it, and He punishes those who abandon it. It is also because it was commanded that the obligatory prayer be offered in congregation and in a brief manner, in consideration of those who are sick, those who are in need, and so on. As for the supererogatory and voluntary prayer, a person can prolong it as much as he is able to. Thus, every prayer retains its advantage and merit. In the Hadīth: The merit of prolonged qunūt and standing for recitation in prayer, along with humility and supplication.
