Al-Kāfi - Volume 7 > Inheritance of the Crying Newborn Child
Hadith #2

2- عَلِيٌّ عَنْ أَبِيهِ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ رِبْعِيٍّ قَالَ سَمِعْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) يَقُولُ فِي السِّقْطِ إِذَا سَقَطَ مِنْ بَطْنِ أُمِّهِ فَتَحَرَّكَ تَحَرُّكاً بَيِّناً يَرِثُ وَيُورَثُ فَإِنَّهُ رُبَّمَا كَانَ أَخْرَسَ.

2. Ali has narrated from his father from Hammad ibn ‘Isa from Rib‘iy who has narrated the following: “I once heard abu ‘Abd Allah, ‘Alayhi al-Salam, saying, ‘If a miscarried child falls off the womb of his mother and moves with clear movement, he inherits and is inherited; perhaps he is speechless so that he did not cry.’”
