Anas bin Malik (may Allah be pleased with him) narrates: “Jibreel (peace be upon him) came to the Prophet ﷺ with a white glass in which there appeared a spot the size of a dot. The Prophet ﷺ asked: ‘What is this?’ Jibreel (peace be upon him) said: ‘This is Friday, through which you ﷺ and your ummah have been granted excellence. The Jews and Christians are behind you in this. And there is goodness for you in it. On this Friday, there is an hour in which, whatever supplication a believing servant makes for good, it is accepted. And this day is, with us, the Day of Increase (Yawm al-Mazeed).’ The Prophet ﷺ asked: ‘O Jibreel! What is the Day of Increase?’ Jibreel (peace be upon him) said: ‘Your Lord has made a vast valley in Paradise in which there are hills of musk. When Friday comes, Allah sends down as many angels as He wills. And around that valley are pulpits of light, upon which are seats for the Prophets (peace be upon them). These pulpits are covered by golden pulpits, which are adorned with rubies and emeralds. Behind those hills, upon them, sit the martyrs and the truthful. Allah, the Exalted, will say to them: I am your Lord and I have fulfilled My promise to you, now ask of Me and I will grant you. They will say: O our Lord! We ask for Your pleasure. Allah, the Exalted, will say: I am pleased with you, and for you is whatever you desire, and even more from Me. So they will love the Friday due to the goodness they receive from their Lord on it. And this is the day on which your Lord ascended the Throne, and on it Adam (peace be upon him) was created, and on this day the Resurrection will be established.”
