As-Salaam alaikum,
From the teachings of Sheikh Abdullah ed-Dagestani as explained by one of his Mureeds, Sheikh Nazim Adil al-Haqqani, may Allah be Merciful to them both, death means to be invisible in this world; to disappear from it and reappear in the Heavens. This is the meaning of death to the Awliya. Remembrance of that gives us more spiritual power. When your spirit leaves your body, it will immediately be in its Heavenly Station. Our soul is waiting, like a bird in a cage, to be free.

When a man knows the truth of death, he no longer fears it, but waits for it. This knowledge gives us love to reach our Heavenly home and also a way. We have it in Hadith where the Prophet, Sallallahu alaihi Wasallam, said that the way to meet your Lord is death. If you don't like death, you don't want to meet your Lord.!

All real believers must, therefore, like death-- for it is the way to the Heavens. Thinking of death gives more power to our faith. The love of Allah is the power of our faith, the spirit of our faith. If you haven't any love for Allah, then you cannot have any faith. It is impossible.
