All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Our answer to your question is found in the Saying Allah (which means): {And if you fear privation, Allah will enrich you from His bounty if He wills. Indeed, Allah is Knowing and Wise.} [Quran 9:28], and in the saying of the Prophet : "The Holy Spirit (Jibreel [Gabriel]) has inspired to me that no soul will die until it has completed its appointed term and received its provision in full, so fear Allah and do not be desperate in seeking sustenance, and no one of you should be tempted to seek sustenance by means of committing sin if it is slow in coming to him, because what is with Allah can only be attained by obeying Him." [Ibn Mardawayh, and Al-Albaani classified it as sound]
So fear Allah in what you sell and don’t be deceived by the whispers of the devil that you will lose customers if you stop selling what is not permissible; even if selling it brings an abundant profit and will bring many customers.
Allah Says (what means): {Satan threatens you with poverty and orders you to immorality, while Allah promises you forgiveness from Him and bounty. And Allah is all-Encompassing and Knowing.} [Quran 2: 268]
Whoever abandons something for the sake of Allah, then Allah will compensate him with something better.
