“Get yourself out of this limited world of diseases to the wide world of the hereafter, which has what the eyes have never seen. Nothing is impossible there, and love is not lost.

O you who sold yourself for the sake of something that will cause you suffering and pain, and which will also lose its beauty, you sold the most precious item for the cheapest price, as if you neither knew the value of the goods nor the meanness of the price. Wait until you come on the Day of mutual loss and gain and you will discover the injustice of this contract.

"There is no God but Allah" is something that Allah is buying. Its price is Paradise, and the Messenger is its agent, and you will be pleased to part with a small part of this worldly life to obtain it. The part you lose is a small part of something that as a whole is not worth a mosquito’s wing.
