Tawakkal, the sign of a believer.

 Tawakkal, the sign of a believer. 

Alhamdulillah, the word tawakkal came from wakeel meaning trust. 

This is one of the sign of a believer. 

Allah says, 

Aal-e-Imran 3:122

When two parties among you were about to lose courage, but Allāh was their ally; and upon Allāh the believers should rely.

This was during the battle of Badr, when the believers met, the pagans were 1000 in numbers while the believers were 313 in numbers, but because they had trust and faith in Allah, they saw the 1000 people small in their eyes. 

This is because od tawakkal, trust in Allah. 

Aal-e-Imran 3:159

So by mercy from Allāh, [O Muḥammad], you were lenient with them. And if you had been rude [in speech] and harsh in heart, they would have disbanded from about you. So pardon them and ask forgiveness for them and consult them in the matter. And when you have decided, then rely upon Allāh. Indeed, Allāh loves those who rely [upon Him].

This ayah was revealed upon rasulullah salla Allahu alayhi wasalam to seek counsel with his companions but when he has taken a decision to rely upon Allah and indeed unto Allah do the believers put their hope upon. 

And tawakkal is the source of everything. 

If one wants peace and joy of life, wealth and power, let him hold unto tawakkal. 

Allah says, 

Aal-e-Imran 3:160

إِن يَنصُرْكُمُ ٱللَّهُ فَلَا غَالِبَ لَكُمْۖ وَإِن يَخْذُلْكُمْ فَمَن ذَا ٱلَّذِى يَنصُرُكُم مِّنۢ بَعْدِهِۦۗ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ

If Allāh should aid you, no one can overcome you; but if He should forsake you, who is there that can aid you after Him? And upon Allāh let the believers rely.

As reported in hadith,

Narrated Ibn `Abbas,

Allah's Messenger (ﷺ) said, 'Nations were displayed before me; one or two prophets would pass by along with a few followers. A prophet would pass by accompanied by nobody. Then a big crowd of people passed in front of me and I asked, Who are they Are they my followers?" It was said, 'No. It is Moses and his followers It was said to me, 'Look at the horizon.'' Behold! There was a multitude of people filling the horizon. Then it was said to me, 'Look there and there about the stretching sky! Behold! There was a multitude filling the horizon,' It was said to me, 'This is your nation out of whom seventy thousand shall enter Paradise without reckoning.' "Then the Prophet (ﷺ) entered his house without telling his companions who they (the 70,000) were. So the people started talking about the issue and said, "It is we who have believed in Allah and followed His Apostle; therefore those people are either ourselves or our children who are born m the Islamic era, for we were born in the Pre-lslamic Period of Ignorance.'' When the Prophet (ﷺ) heard of that, he came out and said. "Those people are those who do not treat themselves with Ruqya, nor do they believe in bad or good omen (from birds etc.) nor do they get themselves branded (Cauterized). but they put their trust (only) in their Lord " On that 'Ukasha bin Muhsin said. "Am I one of them, O Allah'sMessenger (ﷺ)?' The Prophet (ﷺ) said, "Yes." Then another person got up and said, "Am I one of them?" The Prophet (ﷺ) said, 'Ukasha has anticipated you."
