Abul Ja‘d ad-Dumairi reported God’s Messenger as saying, “If anyone fails to observe the prayers on three Fridays through holding it in small esteem,'God will seal up his heart.”
Abu Dawud, Tirmidhi, Nasa’i, Ibn Majah and Darimi transmitted it. Malik transmitted it from Safwan b. Sulaim, and Ahmad from Abu Qatada.
Ibn ‘Umar and Abu Huraira said they heard God’s Messenger say on the beams of his pulpit, “People must cease to neglect the Friday prayers, or God will seal up their hearts and they will be among the negligent.”
Samura b. Jundub reported God’s Messenger as saying, “If anyone omits the Friday prayer without excuse he must give a dinar in alms, or if he does not have as much, half a dinar.”
Anas said that when Rajab came God’s Messenger said, “O God, bless us in Rajab and Sha'ban and bring us to Ramadan.” He also quoted him as saying, “Thursday night is a very bright night and Friday is a shining day.”
