Physical relationships in the name of friendship
Boys and girls start living with each other in the name of friendship and this “friendship” leads to illicit relationships (May Allah protect us all from this). Physical relationship between boys and girls is strictly forbidden.
Islamic guidelines and rules of the Shariah cannot be violated in the name of friendship. It is mentioned in Surah Taha:
And surely he who bears the burden of wrongdoing will crumble to failure.
(Surah Taha: 20:111)
Illicit physical relations is nothing but adultery and a great sin and a Faithful (Momin) can’t commit such an act. If anyone denies this mischief then Faith (Iman) will be out of him. There is a Hadith in Sahih Bukhari and Sahih Muslim:
Translation: It has been narrated on the authority of Hadhrat Abu Hurairah (May Allah be well pleased with him) that the Holy Prophet (Sallallahu alaihi wa sallam) said: At the time when an adulterer is committing adultery, he (or she) is not a complete believer (Momin). (Sahih Bukhari, Kitab Ul Madhalim, Babun Nuhba Bighairi Idhni Sahibihee, Hadith No. 2475; Sahih Muslim, Kitab Ul Iman, Babu Bayani Nuqsanil Imani Bil Ma’asi, Hadith No. 211)
Describing how vile adultery is, the Holy Prophet (Sallallahu alaihi wa sallam) has declared it the worst sin after ascribing partners to Almighty Allah (Shirk). He (Sallallahu alaihi wa sallam) said:
Translation: After ascribing partners to Allah, there is no sin worst than casting one’s seed in a womb, which was not permissible for that man. (Jame’ Ul Ahadith, Hadith No. 20456)
