[23].Surah Al-Muminun [The Believers]: Ayat 76-77

৭৬) তাদের অবস্থা হচ্ছে এই যে, আমি তাদের দুঃখ-কষ্টে ফেলে দিয়েছি, তারপরও তারা নিজেদের রবের সামনে নত হয়নি এবং বিনয় ও দীনতাও অবলম্বন করে না ৷
৭৭) তবে যখন অবস্থা এমন পর্যায়ে পৌঁছে যাবে যে, আমি তাদের জন্য কঠিন আযাবের দরজা খুলে দেবো তখন অকস্মাত তোমরা দেখবে যে, এ অবস্থায় তারা সকল প্রকার কল্যাণ থেকে হতাশ হয়ে পড়েছে ৷

Ayat 76. And indeed We seized them with punishment, but they humbled not themselves to their Lord, nor did they invoke (Allah) with submission to Him. 

Ayat 77. Until, when We open for them the gate of severe punishment, then lo! They will be plunged into destruction with deep regrets, sorrows and in despair. 

[Tafseer] of ayat 76. We inflicted Punishment on them, but they humbled not themselves to their Lord, nor do they submissively entreat (Him)!- Some Commentators understand the battle of Badr to be meant here: if so, this particular verse would be of the Madinah period. But it is better to understand it as referring to the same "distress" as in the preceding verse, or to punishments in general, which obstinate sinners refuse to take as warnings given to them to mend their ways and turn in repentance to Allah. Ayat 77. Until We open on them a gate leading to a severe Punishment: then Lo! they will be plunged in despair therein! If the little trials in the present life will not open their eyes, will great trials do so? Unfortunately they only cause in the wicked a feeling of despair. In the final Punishment after the Judgment, it will be too late for them to repent, and despair will be their only lot.  

Hazrat Umar (May Allah be pleased with him) said: I heard Messenger of Allah [SAWW](PBUH) saying: "If you all depend on Allah with due reliance, He would certainly give you provision as He gives it to birds who go forth hungry in the morning and return with full belly at dusk".

[At-Tirmidhi Hadith # 2344]. 

Lesson : as mentioned above in Surah Al-Muminun Ayat 77."They will be plunged into destruction with deep regrets, sorrows and in despair". Trust in Allah does not mean that one should not give any importance to material resources. What it really means is that along with their due importance, one should have full trust in Allah. Without His Will, material resources are of no avail. But nevertheless it is necessary to have material resources because their procurement is also ordained by Him. Birds do not keep sitting in their nests for food but fly out in search of it.
