The real meaning of "trust", here, is leaving one's tasks in His hands and selecting Him as one's only true help in the times of adversity. The significance of trust does not imply abandoning one's struggle, rather, it means that once man has done his utmost in struggling and has not been able to solve his difficulty, he must not be upset. He must rely upon Allah's favor, support, and seek help from His pure Essence. He must have fortitude and continue on in his everlasting struggle.
The above holy verse says: " And Moses said: "O my people! If you have(really)believed in Allah, then put trust in Him(alone)if you have surrendered(unto Him). " Commentary : Verse 85 (85) فَقالُوا عَلَى اللَّهِ تَوَكَّلْنا رَبَّنا لا تَجْعَلْنا فِتْنَةً لِلْقَوْمِ الظَّالِمينَ " Then they said: 'In Allah(alone)we have put our trust. 'Our Lord! Make us not(subject)to a trial for the unjust people'. " Commentary : These truthful believers accepted Moses' call to trust in Allah.
They said that only in Allah they put their hopes and trust. The verse says: " Then they said: 'In Allah(alone)we have put our trust. ..." Then, they supplicated Him to relieve them from the wickedness and vices of their enemies as well as the pressure they were imposing upon them. They invocated Him not to set them to become rebellious like the oppressors nor put them under their control and influence. The above holy verse continues saying: "... 'Our Lord!
Make us not(subject)to a trial for the unjust people'. " Commentary : Verse 86 (86) وَ نَجِّنا بِرَحْمَتِكَ مِنَ الْقَوْمِ الْكافِرينَ "And deliver us by your Mercy from the disbelieving people. " Commentary : They supplicated that Allah(s. w. t.)might relieve them, by His Own Grace, from the grips of the infidels, i. e. Pharaonic nation who had been enslaving them, allocating hard work and imposing mean jobs upon them. The verse says: "And deliver us by your Mercy from the disbelieving people.
" Commentary : Verse 87 (87) وَ أَوْحَيْنا إِلى مُوسى وَ أَخيهِ أَنْ تَبَوَّءا لِقَوْمِكُما بِمِصْرَ بُيُوتاً وَ اجْعَلُوا بُيُوتَكُمْ قِبْلَةً وَ أَقيمُوا الصَّلاةَ وَ بَشِّرِ الْمُؤْمِنينَ " And We revealed to Moses and his brother, saying: 'Provide houses for your people in Egypt, make your houses into places of worship, and keep up prayer: and give glad tidings to the believers'.
