If we feel something is missing in life, actually we just forget. Forgetting that everything is left for safekeeping and never belongs, meaning nothing is ever lost ..
مَا عِنْدَكُمْ يَنْفَدُ ۖ وَمَا عِنْدَ اللَّهِ بَاقٍ ۗ ~ النحل ٩٦
What is by your side disappears, and what is with Allah is eternal.
