اَلسَّلَامُ عَلَيْكُم وَرَحْمَةُ اَللهِ وَبَرَكَاتُهُ I believe firmly that only Allah is the provider and have complete Tawakkul upon him. I am working hard to earn halal but then, when I see no results or there is delay I become sad, Is this feeling of being overwhelmed/sadness opposing Tawakkul?

Ustadh AbdulAziz al-Haqqan

No it is natural sadness but no need to feel sad akhi, have full trust of Allah.
