The best among you
The Prophet Muhammad (salallahu alaihi wasallam) said, "Shall I tell you who are the best among you? The best of you are those who when seen are a means of Allah being brought to mind."
[Al-Tirmidhi, Hadith 1302]

Spend righteously and teach wisdom
The Prophet Muhammad (salallahu alaihi wasallam) said, "There are two kinds of people worth envying: someone whom Allah has made rich and who spends his money righteously, and someone whom Allah has given wisdom and who acts according to it and teaches it to others."
[Sahih Al-Bukhari, Volume 9, Hadith 255]

Thank people
The Prophet Muhammad (salallahu alaihi wasallam) said, "He who does not thank people does not thank Allah."
[Al-Tirmidhi, Hadith 897]

Teaching by example
Narrated Abu Qatadah - "We were sitting in the masjid when the Prophet Muhammad came upon us carrying his great granddaughter. She was a child and he was carrying her on his shoulder. The Prophet led the people in prayer while she was on his shoulder. When he bowed in prayer, he put her down and picked her up when he got up. He kept on doing this until he finished his prayer."
[Sunan of Abu Dawood, Hadith 353]
Comments on the hadith: "The purpose behind the action of the Prophet (salallahu alaihi wasallam) carrying his great granddaughter in the prayer was to set an example for those who considered having daughters and carrying them around as something bad or shameful. The Prophet....acted differently from them and carried a girl on his neck in the prayer....Making something clear by example is much more effective than a mere precept."
[Fiqh-us-Sunnah, Volume 2, Number 84]

Acts of kindness
The Prophet Muhammad (salallahu alaihi wasallam) said, "Acts of kindness protect one from ruin wrought by evil."
[Fiqh-us-Sunnah, Volume 3, Number 97B]
The Prophet (salallahu alaihi wasallam) also said, "Allah is Kind and He loves kindness. Kindness is not to be found in anything but that it adds to its beauty."
[Sahih Muslim, Hadith 1186 and 1187]

Injustice
The Prophet Muhammad (salallahu alaihi wasallam) said, "If a man suffers injustice and endures it patiently, Allah will grant him strength."
[Fiqh-us-Sunnah, Volume 3, Number 3]

Remember Allah
The Prophet Muhammad (salallahu alaihi wasallam) said, "When any group of people remembers Allah, angels surround them and mercy covers them, tranquility descends upon them, and Allah mentions them to those who are with Him."
[Fiqh-us-Sunnah, Volume 4, Number 102]
"Without doubt, it is the remembrance of Allah that brings tranquility to the heart."
[Holy Qur'an, 13:28]

Visit the sick
The Prophet Muhammad (salallahu alaihi wasallam) said, "Heaven calls out to anyone who visits a sick person: 'You are good and your path is good. May you enter your residence in Paradise.'"
[Fiqh-us-Sunnah, Volume 4, Number 3A]

The golden rule
The Prophet Muhammad (salallahu alaihi wasallam) said, "Do you know who will go first on the Day of Resurrection to the shade of Allah? Those who when given what is right accept it, when asked for something give freely and who judge in favour of others as they do for themselves."
[Al-Tirmidhi, Hadith 1042]

Allah loves you
A man once came to the Prophet Muhammad (salallahu alaihi wasallam) with a sheet of cloth and something in his hand. The man said, "I saw a group of trees and heard the sound of young birds. I took them and put them in my garment. Their mother then came and began to hover around my head. I showed (the chicks) to her and she fell on them. I wrapped them (all) with my garment. They are now with me." The Prophet (salallahu alaihi wasallam) said to his companions, "Are you surprised at the affection of the mother for her young? ... Allah is more affectionate to His servants than a mother to her young ones. Take (the chicks) back and put them where you found them."
[Sunan of Abu Dawood, Hadith 1359]

A friendly word
The Prophet Muhammad (salallahu alaihi wasallam) told his companions, "Save yourselves from (Hell) even if with half of a date (given in charity), and if that is not available then (save yourselves) by saying a friendly word."
[Sahih Al-Bukhari, Volume 8, Hadith 52]

A place in Paradise

Avoid anger
A man once said to the Prophet Muhammad (salallahu alaihi wasallam), "Teach me some words that I can live by. Do not make them too much for me, lest I forget." The Prophet replied, "Do not become angry."
