The Cow - 2:58
Enter this city. Eat therein abundantly from whatever you wish. Enter the gates humbly and speak in friendship so that We may forgive you your faults. We will give more to those who do good.
The believers walk in the earth without ostentation:
Luqman/31:19
Avoid ostentation in your walk and lower your voice. The ugliest sound is that of donkeys.
The Night Journey/17:37
Do not walk arrogantly on the earth; you cannot pierce the earth, nor can you be as tall as the mountains.
The Criterion/25:63
The servants of the Most Merciful are such that they walk in the earth without ostentation. And when the ignorant insult them, they offer peace.
The Women/4:36
Serve Allah and associate with Him nothing and no one. Do good to parents, relatives, orphans, the poor, near neighbors, distant neighbors, companions, travelers, and those to whom your oaths/agreements are due. Allah does not love the arrogant and conceited.
