Assalamualaykum Friend,
We hope you are doing well in both eeman and health.
”أَنَا عِنْدَ ظَنِّ عَبْدِي بِي ، إِنْ ظَنَّ خَيْرًا فَلَهُ ، وَإِنْ ظَنَّ شَرًّا فَلَهُ“ “I am as My servant expects of Me, so if he thinks good of Me then he will have it, and if he thinks evil of Me then he will have it.”
The starting point of Islam is Al-Shahada: saying “La ilaha illa Allah - There is no God but Allah.” It is followed by the continuation: faith, or truly believing in Allah, and all His qualities.
Husn Al-Dhan Billah (حٌسن الظّن بِالله), or thinking positively of Allah (swt), becomes a continuation of the basic pillars that make up faith (iman); which comes with the full realization and understanding of His mercy.
Allah says in Surat Al A’raaf: “My mercy is all-encompassing, it embraces everything.” "ورحمتي وسعت كل شي"
Your relationship with the Creator and the bond and connection you maintain with Him is greatly influenced by what you think of Him and how you believe He sees you. |
