Holy Quran is the last and the final Message from Our Lord Allah to the whole mankind. It is a pure word of God and is retained in its pure and unchanged form since the time it was revealed.
This Book (The Holy Quran) has simple and basic yet very important instruction to lead our life and if we follow these simple instructions from our God (Allah) our life in this world as well as hereafter will get better. These direct instruction for the mankind from Allah are given below along with reference from the Holy Quran:
1. How to Speak With Other People:
And be moderate in your pace, and lower your voice; for the harshest of sounds without doubt is the braying of the ass. ( Suarh Luqman Chapter 31 verse 19)
2. Controlling Ones Anger:
In Surah Al - Imran chapter 3 verse 133-134 Allah gives glad tidings to people among them are the one who restrain when in anger.
3. Respecting the Parents:
Your Lord has decreed that you worship none but Him, and that you be kind to parents. Whether one or both of them attain old age in your life, say not to them a word of contempt, nor repel them, but address them in terms of honor. And out of kindness, lower to them the wing of humility and say: My Lord ! bestow on them your Mercy even as they cherished me in childhood. (Surah Isra Chapter 17 verses 23-24)
And We Have enjoined on man (to be good) to his parents..... (Surah Luqman Chapter 31 verse 14).
4. Be Good To Everyone:
Serve Allah and join not any partners with Him and do good - to parents, kinsfolk, orphans, those in need, neighbors who are near of kin, neighbors who are strangers, the companions by your side, the wayfarer (you meet), and those (slaves) whom your right hand possess. Verily Allah does not like those who are proud and boastful. ( Surah Nisa Chapter 4 verse 36)
5. Do Not Ridicule Others:
O you who believe! Let not some men among you laugh at others; it may be that the (latter) are better than the (former), nor let some women laugh at others; it may be that the (latter) are better than the (former). Nor defame nor be insult each other, nor call each other by offensive nicknames. How bad is it to insult one's brother after having faith. And whoso ever does not repent . then such are indeed wrongdoers ( Surah Hujarat Chapter 49 verse 11).
6. Do Not Take Bribery:
And do not eat up one another's property unjustly, nor give bribery to the rulers, that you may knowingly eat up a part of the property of others sinfully. ( Surah Baqarah Chapter 2 verse 188)
7. Do Not Consume Interest/ Usury:
Those who devour usury will not stand except as stands one whom devil by his touch has driven to madness. That is because they say trade is like usury, but Allah has permitted trade and forbidden usury........ ( Surah Baqarah Chapter 2 verse 275)
