Hazrat Abu Zar Ghaffari [R.A] reports that my beloved friend, Nabi (sallallahu alayhi wasallam) instructed with seven advices:

1. Love the poor and needy and keep close to them.
2. In this world, look at the people below you [i.e. those who possess
less than you in worldly wealth and not those who possess more than
you.]
3. Enjoin family ties and keep relationship with family members even
if they do not.
4. Do not ask anything from any person. [i.e. ask your needs from Allah only]
5. Speak the truth at all times.
6. Not to fear the reproach of any person and bad words of other people.
7. Recite in abundance "Laa hawla wala quwata illa billa hil
Aliyil Azeem", because it is from the treasures of Allah, which is
directly under the Throne of Allah.
