Boycotting sinners

[Abu Dujanah]

as-Salaamu 3alaykum,

Ibn Taymeeyah (Rahimahullaah) said, "The adulterresses/fornicators, homosexuals, those who leave Jihaad, innovators, alchohol drinkers, they do not have sincerity for themselves nor for the Muslims. It is obligatory to boycott them and to not sit with them." (Volume 15 of Majmoo3 al-Fataawaa)

I think its interesting how he grouped those who left Jihaad right after homosexuals (actually the word use is for those who practice sodomy) and before innovators. Of course, the issue of benefits and harms in boycotting is to be taken into consideration like always, and most of the contemporary scholars say boycotting a sinful Muslim in our times is not very effective, but rather he should be advised. Unless the person fears that he will be affected by the sin of the sinful person, then he must boycott him for his own personal good.
