Surah No. 3, Al Imraan, Ayat No. 160
إِن يَنصُرْكُمُ اللّهُ فَلاَ غَالِبَ لَكُمْ وَإِن يَخْذُلْكُمْ فَمَن ذَا الَّذِي يَنصُرُكُم مِّن بَعْدِهِ وَعَلَى
o اللّهِ فَلْيَتَوَكِّلِ الْمُؤْمِنُونَ
If Allah helps you, no one can overcome you; and if He did not help you, who is there after Him who can help you? And in Allah (Alone) let believers put their trust.
Surah No. 58, Al Mujadilah, Part of Ayat No. 10
o وَلَيْسَ بِضَارِّهِمْ شَيْئًا إِلَّا بِإِذْنِ اللَّهِ وَعَلَى اللَّهِ فَلْيَتَوَكَّلِ الْمُؤْمِنُونَ
He (shaitan) cannot harm them, except as Allah permits, and let the believers put their trust in Allah .
Surah No. 64, At Taghabun, Ayat No. 13
o اللَّهُ لَا إِلَهَ إِلَّا هُوَ وَعَلَى اللَّهِفَل ْيَتَوَكَّلِ الْمُؤْمِنُونَ
No one has the right to be worshipped but He, and in Allah (alone), let the believers put their trust.
Surah No. 65, At Talaaq, part of Ayat No. 3
وَمَن يَتَوَكَّلْ عَلَىاللَّهِ فَهُوَ حَسْبُهُ إِنَّ اللَّهَ بَالِغُ أَمْرِهِ
And whosoever puts his trust in Allah, then He will be sufficient for him. In fact, Allah will accomplish his purpose.
One of the religious scholar had narrated :
" Once the Prophet (saws) has informed the companions to put their trust with regard to each affair only in Allah ". The very next day one of his companion came riding on a camel and after getting down from it, he asked the Prophet, " shall I tie this camel with a rope to some stationary object or keep my trust in Allah". The Prophet replied "You must tie the camel with a rope and then have trust in Allah and not in the rope "
This clearly means that everyone must make efforts to achieve the objectives and then put trust in Allah only.
