Pray for your brothers when they are away — the angel prays the same for you. The Prophet ﷺ said: “There is no Muslim who supplicates for his brother in his absence but the angel says: ‘Āmīn, and for you the like.’” (Muslim).
العربية: عن أبي الدرداء رضي الله عنه أنّ رسول الله ﷺ قال: «ما مِن عبدٍ مسلمٍ يدعو لأخيه بظهر الغيب إلا قال المَلَك: ولك بمثل». (مسلم).
Keep those you love in your duʿā by name — a good that returns to you as well.
