Allah, Most High, said:
٢١٠ - باب فضل يوم الجمعة ووجوبها والاغتسال لها والطيب والتبكير إليها والدعاء يوم الجمعة والصلاة على النبي - ﷺ - وفيه بيان ساعة الإجابة واستحباب إكثار ذكر الله تعالى بعد الجمعة
Allah, Most High, said:
And when the prayer has been concluded, disperse within the land and seek from the bounty of Allāh, and remember Allāh often that you may succeed.
Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah ﷺ said: "The best day on which the sun has risen is Friday: on it Adam was created, on it he was admitted into Paradise, and on it he was expelled from it." Narrated by Muslim.
And from him (may Allah be pleased with him), who said: The Messenger of Allah ﷺ said: "Whoever performs ablution and does it well, then comes to the Friday prayer, listens attentively and remains silent, will be forgiven what is between him and the next Friday, and three days more. And whoever touches the pebbles has engaged in idle conduct." Narrated by Muslim.
And from him, from the Prophet ﷺ, who said: "The five daily prayers, one Friday to the next Friday, and Ramadan to Ramadan, are an expiation for what is between them, so long as the major sins are avoided." Narrated by Muslim.
And from him, and from Ibn Umar (may Allah be pleased with them all): that they both heard the Messenger of Allah ﷺ saying upon the planks of his pulpit: "Let people desist from neglecting the Friday prayers, or else Allah will seal their hearts, and then they will surely be among the heedless." Narrated by Muslim.
And from Ibn Umar (may Allah be pleased with them both): that the Messenger of Allah ﷺ said: "When one of you comes to the Friday prayer, let him perform ghusl." Agreed upon (by al-Bukhari and Muslim).
And from Abu Sa'id al-Khudri (may Allah be pleased with him): that the Messenger of Allah ﷺ said: "The ritual bath (ghusl) of Friday is obligatory upon everyone who has reached puberty." Agreed upon (by al-Bukhari and Muslim). What is meant by "one who has reached puberty" is the adult who has attained maturity. And what is meant by "obligatory" is an obligation of choice, like a man's saying to his companion: "Your right is binding upon me." And Allah knows best.
And from Samurah (may Allah be pleased with him), who said: The Messenger of Allah ﷺ said: "Whoever performs ablution on Friday, that is fine and good; but whoever performs ghusl, the ghusl is better." Narrated by Abu Dawud and al-Tirmidhi, who said: "A good (hasan) hadith."
And from Salman (may Allah be pleased with him), who said: The Messenger of Allah ﷺ said: "No man performs ghusl on Friday, purifies himself as much as he is able, anoints himself with his oil, or applies some scent from his house, then goes out and does not separate two people, then prays what is prescribed for him, then remains silent when the imam speaks — except that he is forgiven what is between that Friday and the next." Narrated by al-Bukhari.
And from Abu Hurayrah (may Allah be pleased with him): that the Messenger of Allah ﷺ said: "Whoever performs ghusl on Friday like the ghusl for major ritual impurity, then goes early in the first hour, it is as though he offered a camel; whoever goes in the second hour, it is as though he offered a cow; whoever goes in the third hour, it is as though he offered a horned ram; whoever goes in the fourth hour, it is as though he offered a hen; and whoever goes in the fifth hour, it is as though he offered an egg. Then, when the imam comes out, the angels attend, listening to the remembrance." Agreed upon (by al-Bukhari and Muslim). His saying "the ghusl for major ritual impurity" means a ghusl resembling the ghusl for major impurity in its manner.
And from him: that the Messenger of Allah ﷺ mentioned Friday and said: "In it there is an hour during which no Muslim servant, while standing in prayer, asks Allah for something, except that He grants it to him." And he indicated with his hand that it is brief. Agreed upon (by al-Bukhari and Muslim).
And from Abu Burdah ibn Abi Musa al-Ash'ari (may Allah be pleased with him), who said: Abdullah ibn Umar (may Allah be pleased with them both) said: "Did you hear your father narrating from the Messenger of Allah ﷺ concerning the hour of Friday?" He said: I said: "Yes, I heard him say: I heard the Messenger of Allah ﷺ say: 'It is between the imam's sitting down and the completion of the prayer.'" Narrated by Muslim.
On the authority of Aws ibn Aws (may Allah be pleased with him), who said: The Messenger of Allah ﷺ said: "Among the most excellent of your days is Friday, so invoke many blessings upon me on it, for your blessings are presented to me." Narrated by Abū Dāwūd with a sound chain of transmission.
