40 صحيح حديث أَبي ذَرٍّ رضي الله عنه أَنَّهُ سَمِعَ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: لَيْسَ مِنْ رَجُلٍ ادَّعَى لِغَيْرِ أَبيهِ وَهُوَ يَعْلَمُهُ إِلاَّ كَفَرَ، وَمَنِ ادَّعى قَوْمًا لَيْسَ لَهُ فِيهِمْ نَسَبٌ فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ
Sayyiduna Abu Dharr (may Allah be pleased with him) reports that the Noble Prophet (peace and blessings be upon him) said: Whoever knowingly claims someone other than his father as his father, he has committed disbelief; and whoever associates his lineage with a people to whom he has no (blood) relation, then he should take his place in Hell.
