Assalamu Allikum. A thing is troubling me a lot as I am not knowledgeable enough I am very confused so it will be good if you answer fast. Few months ago I was reading about waqf then I felt sad that I have nothing that I can give as waqf then another thought came to my mind that I have my phone. Then I just said something like I'm am making my mobile waqf. Now I am confused if I just made my mobile waqf. If I did are my SIM card and memory card are also part of it as changing numbers will be very problematic and I also rade for waqf to valide one has to hand it over I let my cousin sister grandfather use it will it be like handling over property. As it will be very hard for me to give this phone if it's a valid waqf can't I just give it's might be value in mosque charity box with out letting anyone know.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad, sallallaahu 'alayhi wa sallam, is His slave and Messenger.

Your statement, “I will give my phone as Waqf,” is a promise to make it a Waqf (endowment) and not a binding Waqf, so you are not required to do anything. Whoever holds a sincere intention to give in charity but does not have money to spend in charity therefrom, Allah, The Exalted, grants him the reward for that charity (for his sincere intention). It was narrated on the authority of Abu Kabshah Al-Anmaari that he heard the Prophet say: “The worldly life is only for four categories of people … (and he mentioned of them) … a slave whom Allah blesses with knowledge but not with wealth. So he holds a truthful intent, saying: ‘If I had wealth, I would perform the (good) deeds performed by so-and-so with it.’ He is rewarded for his intention, and therefore their rewards are the same…” [Ahmad and At-Tirmithi]

Thus, if you hold a truthful intention to make a Waqf and you do not have wealth to do so, it is hoped that Allah, The Exalted, would reward you for your intention by His Grace and Favor.

Allah Knows best.
