The Sufficient (Vol 7) · Hadith 485 (#Ḥadīth #4)

4- ابْنُ مَحْبُوبٍ عَنْ عَبْدِ اللهِ سِنَانٍ قَالَ سَمِعْتُ أَبَا عَبْدِ اللهِ يَقُولُ تَجُوزُ شَهَادَةُ الْقَابِلَةِ فِي الْمَوْلُودِ إِذَا اسْتَهَلَّ وَصَاحَ فِي الْمِيرَاثِ وَيُوَرَّثُ الرُّبُعَ مِنَ الْمِيرَاثِ بِقَدْرِ شَهَادَةِ امْرَأَةٍ وَاحِدَةٍ قُلْتُ فَإِنْ كَانَتَا امْرَأَتَيْنِ قَالَ تَجُوزُ شَهَادَتُهُمَا فِي النِّصْفِ مِنَ الْمِيرَاثِ.

4. Ibn Mahbub has narrated from ‘Abd Allah ibn Sinan who has narrated the following: “I once heard abu ‘Abd Allah , saying, ‘The testimony of a female nurse about the crying of a newborn at the time of birth is effective for one-fourth of the legacy proportionate to the testimony of one woman.’ I then asked, ‘What happens if they are two women?’ He (the Imam) said, ‘It is effective for one-half of the legacy.’”
