In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
If a beneficiary rejects the Waqf, he will not be entitled to the proceeds of the Waqf. In such a scenario, the Waqf still remains valid and the proceeds or use of the Waqf will be channelled for general charitable purposes. [Diraasat an al-Waqf by Dr Salah Abul Haj]
And Allah Alone Knows Best
