4. Ahmad ibn Muhammad al-‘Asemiy has narrated from Ali ibn al-Hassan ibn Faddal from Ali ibn Asbat from his uncle, Ya’qub ibn Salim from Muhammad ibn Muslim who has said the following:

“Abu Ja‘far , has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘The existence of a virtuous woman is like an al-A‘sam crow which is so rare to find.’ It was asked, ‘What is an al- A‘sam crow?’ He (the Messenger of Allah) replied, ‘It is that which is very rare to find.’ He (the Messenger of Allah) said, ‘It is the one which has one white leg.’”
