Hazrat Abu Qilaabah said: “Do not sit with the people of Ahwaa (lust, worldly-craving, those who pursue name and fame) nor dispute with them for I fear that they will plunge you into their deviation or confuse you about what you know.”
Hazrat Amr Bin Qais Al-Malaaee said: “Do not associate with a man of deviation, for he will make your heart crooked.”
Hazrat Ibraaheem Nakah’i said: “Do not sit with the people of Ahwaa, for verily, association with them eliminates the Noor of Imaan from the heart, it despoils the beauty of the face and it generates malice in the hearts of the Mu’mineen.”
Hazrat Ismaaeel Bin Ubaidullah said: “Do not sit with a man of Bid’ah, for he will cause your heart to be diseased.”
Hazrat Fudhail Bin Iyaadh said: “He who honours a man of Bid’ah, verily he has aided in destroying the Deen. He who smiles with a Bid’ati, verily he has considered Allah’s revelation to Muhammad (Sallallahu alaihi wasallam) to be insignificant. He who marries his daughter to a Bid’ati, has severed his ties with her. He who follows the Janaazah of a Bid’ati, remains under the Wrath of Allah until his return.”
“The sign of Nifaaq (hypocrisy) of a man is that he sits with a man of Bid’ah. He who associates with a man of Bid’ah, is not granted Hikmah (wisdom). Don’t sit with a man of Bid’ah, for I fear La’nat (Allah’s Curse) settling on you. Allah obliterates the deeds of a person who loves a Bid’ati, and Allah eliminates the Noor of Islam from his heart. It is not possible for a man of the Sunnah to incline to a Bid’ati except if there is Nifaaq in him.”
