سنن النسائي

It was narrated that Umaimah bint Ruqaiqah said: "I came to the Prophet (ﷺ) with some other Ansari women to give our pledge. We said: 'O Messenger of Allah, we give you our pledge that we will not associate anything with Allah, we will not steal, we will not have unlawful sexual relations, we will not utter slander, fabricating from between our hands and feet, and we will not disobey you in goodness.' He said: 'As much as you can and are able.' We said: 'Allah and His Messenger are more merciful toward us. Com, let us give you our pledge, O Messenger of Allah! The Messenger of Allah (ﷺ) said: 'I do not shake hands with women. Rather my word to a hundred women is like my word to one woman."'
