وَعَلٰی اٰلِكَ وَاَصۡحٰبِكَ يَا حَبِيۡبَ اللّٰه                                                                                               اَلصَّلٰوةُ وَالسَّلَامُ عَلَيۡكَ يَا رَسُوۡلَ اللّٰه
وَعَلٰى اٰلِكَ وَاَصۡحٰبِكَ يَا نُوۡرَ اللّٰه                                                                                                              اَلصَّلٰوةُ وَالسَّلَامُ عَلَيۡكَ يَا نَبِيَّ اللّٰه
نَوَيۡتُ سُنَّتَ الۡاِعۡتِكَافِ

I make the intention of Sunna iꜤtikāf

Dear Islamic brothers! Whenever you enter a masjid, make the intention of iꜤtikāf, as you shall continuously gain the reward of iꜤtikāf for as long as you stay inside. Normally, when we are in a masjid, Islamic law does not permit us to eat, drink, sleep, have suḥūr or ifṭār, or even give permission for us to eat, drink, sleep, have suḥūr or ifṭār, and not even to drink Zamzam water or the water on which prayers have been made. Yet, if the intention of iꜤtikāf is made, all these actions will become permissible. One should not make this intention only to eat, drink, or sleep. This intention should instead be made to please Allāh.

As mentioned in Fatāwā Shāmī:

If someone wants to eat, drink, or sleep in a masjid, he should make the intention to observe iꜤtikāf and perform the dhikr of Allāh for some time. Then, he may proceed as he wishes (i.e., now if he wants to eat, drink, or sleep, he can do so).
