Sir, I heard on a video that if two married people are about to have intercourse and don’t say “Bismillah“, then a Jinn will the father of that child. Are there signs for that child to know if he or she is hybrid? Just in curiosity.
The hadith clearly states in Bukhari and Muslim from Ibn `Abbas (r) that the Prophet — upon him blessings and peace — said: “If each seeks from Allah protection with this duaa against Satan at the time of intercourse and Allah grants a child, Satan will not be able to hurt that child forever.”
لَوْ أَنَّ أَحَدَهُمْ إِذَا أَرَادَ أَنْ يَأْتِيَ أَهْلَهُ قَالَ بِاسْمِ اللَّهِ اللَّهُمَّ جَنِّبْنَا الشَّيْطَانَ وَجَنِّبْ الشَّيْطَانَ مَا رَزَقْتَنَا ، فَإِنَّهُ إِنْ يُقَدَّرْ بَيْنَهُمَا وَلَدٌ فِي ذَلِكَ لَمْ يَضُرَّهُ شَيْطَانٌ أَبَدًا
The hurt which is mentioned in the hadith may be understood either in spiritual, moral and religious terms, or in physical terms. Examples of the latter are physical ailments and examples of the former are an intractable character such as inordinate anger and disobedience.
