The Incident of the People of the Trench

وَعَلٰى 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 Sunnah iꜤtikāf.

Dear Islamic brothers! Whenever you enter a masjid, make the intention of iꜤtikāf, for you will then continuously gain the reward of iꜤtikāf as long as you stay inside. Remember, eating, drinking, sleeping, having saḥūr or ifṭār, or even drinking Zamzam water or the water upon which prayers have been recited is not permitted inside a masjid. If the intention of iꜤtikāf is made, all of these acts become permissible. One should not make this intention solely to eat, drink, or sleep; rather, it should be made to please Allah.

As mentioned in Fatāwā Shāmī:

If somebody wishes to eat, drink, or sleep in a masjid, he should make an intention of iꜤtikāf and engage in the dhikr of Allah 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).

The Excellence of reciting Ṣalāt upon the Beloved Prophet صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم

The beloved Prophet صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم said:

اِنَّ اللّٰہَ وَکَّلَ بِقَبْرِیْ مَلَکًااَعْطَاہُ اَسْمَاعَ الْخَلَائِقِ فَلَا یُصَلِّیْ عَلَیَّ اَحَدٌ اِلٰی یَوْمِ الْقِیَامَۃِ اِلَّا اَبْلَغَنِیْ بِاسْمِہٖ وَاسْمِ اَبِیْہ  ِہذَا فُلانُ بْنُ فُلانٍ قَدْ صَلّٰی عَلَیْکَ
