"Keep company of the God-conscious. Do not look at the glitter of Life"

وَٱصۡبِرۡ نَفۡسَكَ مَعَ ٱلَّذِينَ يَدۡعُونَ رَبَّہُم بِٱلۡغَدَوٰةِ وَٱلۡعَشِىِّ يُرِيدُونَ وَجۡهَهُ ۥ‌ۖ وَلَا تَعۡدُ عَيۡنَاكَ عَنۡہُمۡ تُرِيدُ زِينَةَ ٱلۡحَيَوٰةِ ٱلدُّنۡيَا‌ۖ وَلَا تُطِعۡ مَنۡ أَغۡفَلۡنَا قَلۡبَهُ ۥ عَن ذِكۡرِنَا وَٱتَّبَعَ هَوَٮٰهُ وَكَانَ أَمۡرُهُ ۥ فُرُطً۬ا
And keep yourself patiently with those who call on their Lord morning and evening, seeking His Face; and let not your eyes pass beyond them seeking the pomp and glitter of this Life; nor obey any whose heart We have permitted to neglect the remembrance of Us, one who follows his own desires, whose case has gone beyond all bounds.

(Qur'an 18:28)

This Aayah teaches us 3 lessons:
1) Sit with those who remember Allah, who praise Him, and call on Him, whether rich or poor, strong or weak. Make yourself patiently content with sitting with those people, even if they may be poor and weak.
2) Do not be greedy about the riches and luxury of the world. Do not seek the people of nobility and wealth instead.
3) Do not obey or admire the way of those who are distracted by this world from being committed to the religion and from worshipping their Lord.
