“The truth is that trust in God alone is the one thing that can make man succeed and achieve his goals. Allah the Exalted says:
وَمَنۡ یَّتَوَکَّلۡ عَلَی اللّٰہِ فَہُوَ حَسۡبُہٗ
“[And he who puts his trust in Allah — He is sufficient for him (Surah at-Talaq, Ch. 65: V. 4)].
“Allah becomes sufficient for him who puts his trust in Allah the Exalted, provided he progresses in everything honestly with a sincere heart and with the true understanding of trust in God. And he should be patient and steadfast. He should not withdraw by becoming intimidated by adversities. This world is a temporary, transient place as is everything in it and so too are the affairs associated with it. Therefore, it is essential for man to grieve over it less and be more concerned about the Hereafter. If concern for religion comes to prevail over man, God Himself becomes the surety for his worldly affairs.”
