All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
There is no evidence as far as we know, that whoever does not pray three consecutive Friday prayers out of laziness goes out of the fold of Islam.
The threat that is mentioned in regard to not performing the Friday prayer is the saying of the Prophet : “Whoever misses three Friday prayers out of negligence, Allaah will seal his heart.” [Ahmad] The expression ‘Allaah will seal his heart’ means that Allaah will prevent good from reaching it as interpreted by the scholars . This is peculiar to the one who is obliged to perform the Friday prayer because a woman, a slave, a young person and a traveler are not obliged to perform the Friday prayer. For more benefit, please refer to Fatwa 117037.
However, there is no doubt that abandoning the Friday prayer even once without a sound reason is a great sin that requires one to repent to Allaah.
For more benefit on the ruling of abandoning the Friday prayer, please refer to Fataawa 91358 and 88869.
In any case, abandoning the Friday prayer even if this is for a long time is not a sin that takes a person out of the fold of Islam.
