Hadith.534 - When the Messenger of Allah صلى الله عليه وعلى آله وسلم would pass by graves, he would say:
Al-salāmu ‘alaykum min diyāri qawmin mu’minīn, wa innā in shā’a Allāhu bikum lāḥiqūn
'Peace be upon you, O’ dwellers of the homes of believers. Indeed, if Allah سبحانه وتعالى wills, we shall join you.'"
