Ayesha reported,

The Messenger of Allah ﷺ used to test the believing women with this verse, "Believers, when believing women come to you as emigrants, examine them... to Forgiving, Merciful" [Mumtahanah 60:10–12].Urwa said that Ayesha said, "Whichever of them affirmed this condition, the Messenger of Allah ﷺ would say to her, 'I have accepted your pledge,' speaking the words to her only. By Allah, his hand never touched the hand of any woman in the pledge of allegiance. He took their pledge solely through his spoken word."

قال عروة

فأخبرتني عائشة

أن رسول الله ﷺ كان يمتحنهن بهذه الآية {يا أيها الذين آمنوا إذا جاءكم المؤمنات مهاجرات فامتحنوهن} إلى {غفور رحيم} قال عروة قالت عائشة فمن أقر بهذا الشرط منهن قال لها رسول الله ﷺ قد بايعتك كلاما يكلمها به والله ما مست يده يد امرأة قط في المبايعة وما بايعهن إلا بقوله
