✅ Answer: Please pay attention to the following narrations:

1 جَعْفَرِ بْنِ مُحَمَّدٍ علیهما السلام قَالَ: عَلَامَاتُ وَلَدِ الزِّنَا ثَلَاثٌ سُوءُ الْمَحْضَرِ و الْحَنِینُ إِلَی الزِّنَا و بُغْضُنَا أَهْلَ الْبَیْتِ

📚 Amali al-Saduq p. 204

Imam Sadiq (peace be upon him) said: The signs of an illegitimate child are three: evil companionship, inclination and desire for fornication, and hatred of us, the Ahl al-Bayt.

2️⃣ The Messenger of Allah (peace be upon him and his family) said: He who loves us, the Ahl al-Bayt, should praise God for the first blessing. It was said: What is the first blessing? He said: Purity of birth, and no one loves us except a person whose birth is pure.

📚 Ilal al-Shara'i p. 58

3 عَنْ أَمِیرِ الْمُؤْمِنِینَ قَالَ قَالَ رَسُولُ اللَّهِ صلی الله علیه و آله یَا عَلِیُّ مَنْ أَحَبَّنِی وَ أَحَبَّکَ وَ أَحَبَّ الْأَئِمَّةَ مِنْ وُلْدِکَ فَلْیَحْمَدِ اللَّهَ عَلَی طِیبِ مَوْلِدِهِ فَإِنَّهُ لَا یُحِبُّنَا إِلَّا مَنْ طَابَتْ وِلَادَتُهُ وَ لَا یُبْغِضُنَا إِلَّا مَنْ خَبُثَتْ وِلَادَتُهُ

📚 Amali al-Saduq p. 284

The Messenger of Allah (peace be upon him and his family) said: O Ali, he who loves me and you and the Imams from your children should praise God for his pure birth, for no one loves us except a person whose birth is pure, and no one hates us except a person whose birth is foul and impure.

4 عَنْ عَلِیٍّ علیه السلام قال قال رَسُول اللَّه صلی الله علیه و آله مَنْ لَمْ یُحِبَّ عِتْرَتِی فَهُوَ لِإِحْدَی ثَلَاثٍ إِمَّا مُنَافِقٌ و إِمَّا لِزِنْیَةٍ و إِمَّا امْرُؤٌ حَمَلَتْ بِهِ أُمُّهُ فِی غَیْرِ طُهْرٍ

📚 Khisal Vol. 1, p. 54

The Messenger of Allah (peace be upon him and his family) said: He who does not love my family is one of these three persons: either he is a hypocrite, or he is born out of wedlock, or his mother conceived him during her menstruation.

5️⃣ Imam Baqir said: A man who had the characteristic of 'len' (ma'bun) came to Ali (peace be upon him) and said: I love you, the Ahl al-Bayt, and some people also praised and commended this man. Ali (peace be upon him) said: You have lied! A effeminate person, nor a cuckold, nor an illegitimate child, nor a person whose mother conceived him during her menstruation, loves us. He said: That man left, and when the battle of Siffin happened, he was killed with Mu'awiyah.

📚 Qurb al-Isnad

6️⃣ In the hadith of Ali's encounter with Iblis (may Allah's curse be upon him), Iblis said:

وَ اللَّهِ یَا عَلِیُّ إِنِّی لَأُحِبُّکَ جِدّاً و مَا أَبْغَضَکَ أَحَدٌ إِلَّا شَرِکْتُ أَبَاهُ فی أُمِّهِ فَصَارَ وَلَدَ زِناً

O Ali, by God, I truly love you, and no one hates you except that I have participated with his father in his mother, which results in him being an illegitimate child.

📚 Uyun Akhbar al-Reza p. 229

7 قال النبی صلی الله علیه و آله صَدَقَ یا عَلِیُّ لَا یُبْغِضُکَ مِنْ قُرَیْشٍ إِلَّا سِفَاحِیٌّ و لَا مِنَ الْأَنْصَار إِلَّا یَهُودِیٌّ و لَا مِنَ الْعَرَبِ إِلَّا دَعِیٌّ و لا مِنْ سَائِرِ النَّاسِ إِلَّا شَقِیٌّ و لَا مِنَ النِّسَاءِ إِلَّا سَلَقْلَقِیَّةٌ و هی الَّتِی تَحِیضُ مِنْ دُبُرِهَا

📚 Ilal al-Shara'i p. 58

The Messenger of Allah (peace be upon him and his family) said in a hadith: O Ali, no one from Quraysh hates you except an adulterer, and no one from the Ansar except a Jew, and no one from the Arabs except an illegitimate child, and no one from other people except an unfortunate person, and no woman except a 'salqaliqa', and she is a woman who menstruates from her anus.

8 عن الصادق فی حدیث :إِنَّ الرَّجُلَ إِذَا دَنَا مِن الْمَرْأَةِ و جَلَسَ مَجْلِسَهُ حَضَرَهُ الشَّيْطَانُ فَإِنْ هُو ذَكَر اسْمَ اللَّهِ تَنَحَّى الشَّيْطَانُ عَنْهُ وَ إِنْ فَعَلَ وَ لَمْ يُسَمِّ أَدْخَل الشَّيْطَان ذَكَرَهُ فَكان الْعَمَلُ مِنْهُمَا جَمِيعا و النُّطْفَةُ وَاحِدَةٌ قُلْتُ فَبِأَيِّ شَيْ ءٍ يُعْرَفُ هذا جُعِلْتُ فِدَاكَ قَال بِحُبِّنَا و بُغْضِنَا

📚 Tahdhib Vol. 7, p. 407

Imam Sadiq (peace be upon him) said: When a man approaches a woman and sits with her, Satan is present with him, so if he remembers God, he moves away from him, but if that person performs his act and does not mention God's name (does not say Bismillah), Satan also inserts his penis, and the act will be from both of them, and the sperm is one. The narrator said: I said: How is this known? He said: By the love and hatred of us, the Ahl al-Bayt!

✅ There are many narrations on this matter, and you can see that the enemies of the Ahl al-Bayt (peace be upon them) are not only illegitimate children, and a hypocrite, an effeminate person, a person conceived during menstruation, a menstruating woman from her anus, and especially an unfortunate person, and so on, are among those who have hatred for the Ahl al-Bayt (peace be upon them).

✅ However, the participation of Satan in the sperm is also called a type of illegitimacy in hadith 6.

✅ The extreme importance of saying 'Bismillah' at the time of intimacy in hadith 8 should be paid close attention to.
