«من كان له شريك في ربع أو نخل فليس له أن يبيع حتى يؤذن شريكه فإن رضي أخذ وإن كره ترك»
The Prophet (peace and blessings be upon him) said:
"Whoever has a partner in a dwelling or a date-palm orchard should not sell it until he has informed his partner; if he is pleased, he may take it, and if he dislikes it, he may leave it."
