It is reported from Abû Mûsâ Al-Ash’arî – Allah be pleased with him – that he said:

We the Companions of Allah’s Messenger – Allah’s peace and blessings be upon him – never had difficulty in understanding a hadîth except that when we asked ‘Â`ishah we found she had some knowledge about it.

It is reported from Masrûq – Allah have mercy on him – that he said:

We swear by Allah, we have seen senior Companions of Allah’s Messenger – Allah’s peace and blessings be upon him – asking ‘Â`ishah about inheritance laws.
