I send you my most sincere condolences for the loss of you relative. We usually say in these kinds of sad events : "Adhama Allahou ajrakoum" and "Allahou you'tikoum assabr bidoun abr".
Although one might think that these are just words, the formulas that our fellow Muslims just mentionned above bring the muslims together under the name of the ONE God.
