"Has not the time come for those who believe that their hearts become reverent at the remembrance of Allah and what has been revealed of the truth?"

--Surat Al-Hadeed 57:16

أَلَمْ يَأْنِ لِلَّذِينَ آمَنُوا أَن تَخْشَعَ قُلُوبُهُمْ لِذِكْرِ اللَّهِ وَمَا نَزَلَ مِنَ الْحَقِّ

57:16 سورة الحديد 

Yusuf Ali translation of the verse
" Has not the time arrived for the Believers that their hearts in all humility should engage in the remembrance of Allah and of the truth which has been revealed (to them) and that they should not become like those to whom was given Revelation aforetime but long ages passed over them and their hearts grew hard? For many among them are rebellious transgressors."
- Surah Al-Hadeed, verse 16

Note:

Humility and the remembrance of Allah and His Message are never more necessary than in the hour of victory and prosperity.

The men immediately referred to are the contemporary Jews and Christians. To each of these Ummats was given Allah's Revelation, but as time passed, they corrupted it, became arrogant and hard-hearted, and subverted justice, truth, and the purity of Life. But the general lesson is far wider. No one is favoured of Allah except on the score of righteousness. Except on that score, there is no chosen individual or race. There is no blind good fortune or ill fortune. All happens according to the just laws and will of Allah. But at no time is humility or righteousness more necessary than in the hour of victory or triumph.
