Hadith No. 58
الإمام الباقر(علیه السلام): أتىٰ رَجُلٌ مِنَ الأنصارِ رَسولَ اللهِ(صلی الله علیه و آله)، فَقالَ: هذهِ ابنَةُ عَمِّي وامرَأتي لا أعلَمُ إلّا خَيراً، وَ قَد أتَتني بِوَلَدٍ شَديدِ السَّوادِ، مُنتَشِرِ المِنخِرَينِ، جَعدٍ، قَطَطٍ، أفطَسِ الأنفِ، لا أعرِفُ شِبهَهُ في أخوالي ولا في أجدادي!
فَقالَ لاِمرَأَتِهِ: ما تَقولينَ؟ قالَت: لا وَ الّذي بَعَثَكَ بِالحَقِّ نَبِيّاً، ما أقعَدتُ مَقعَدَهُ مِنّي مُنذُ مَلَكَني أحَداً غَيرَهُ.
قال: فَنَكَسَ رَسولُ اللهِِ بِرَأسِهِ مَلِيّاً، ثُمَّ رَفَعَ بَصَرَهُ إلَى السَّماءِ، ثُمَّ أقبَلَ عَلَى الرَّجُلِ فَقالَ: يا هٰذا، إنَّهُ لَيسَ مِن أحَدٍ إلّا بَينَهُ و بَينَ آدمَ تِسعَةٌ و تِسعونَ عِرقاً، كُلُّها تَضرِبُ فِي النَّسَبِ، فَإِذا وَقَعَتِ النُّطفَةُ فِي الرَّحِمِ اضطَربَت تِلكَ العُروقُ؛ تَسأَلُ اللهََ الشُّبهَةَ لَها، فَهٰذا مِن تِلكَ العُروقِ الَّتي لَم يُدرِكها أجدادُكَ و لا أجدادُ أجدادِكَ، خُذ إلَيكَ ابنَكَ. فَقالَتِ المَرأَةُ: فَرَّجتَ عَنّي يا رَسُولَ اللهِِ.
Imam al-Baqir (a.s.) said: “One of the Companions of the Messenger of Allah (s.a.w.) came to him and said: “This is my uncle’s daughter and my wife. I know nothing but good about her. She has brought me a child that is extremely black with large nostrils, fuzzy hair and a flat nose. I know similar to him neither among my uncles nor my ancestors.
He (s.a.w.) asked the man’s wife: “What do you have to say?” She answered: “No, by Him who has appointed you as a prophet in truth, I have never been with anyone else since he has taken me.”
The Messenger of Allah (s.a.w.) cast down his head for a long while then he looked up at the sky, and then he turned to the man and said: “O man! There is no one that does not have between him and Adam ninety nine `irq [genes], and all of them have effects in the descendents. When the sperm arrives into the womb, the `irqs start to move, and they ask Allah that the child be similar to them. Therefore, this is one of the roots that neither your ancestors nor the ancestors of your ancestors have conceived. Take your child.’
The woman said: “O Messenger of Allah! You have solved my problem!”
