"After mentioning ALLAH, and the prayer and salutation upon the Messenger of ALLAH (peace and blessings be upon him), here is some advice for all those seeking advice for themselves, and the advice from the Lord is defined by the words of the Prophet (peace and blessings be upon him) who said: “The deen (religion) is naseehah (advice, sincerity).” We said “To whom?” He (peace and blessings of Allah be upon him) responded: “To Allah, His Book, His Messenger, and to the leaders of the Muslims and their common folk.”
Among this advice, the first is the fear of ALLAH, beside whom there is no Divinity except Him. As Ali (may ALLAH be pleased with him) advised his children with these words: "O my sons, I exhort you to fear ALLAH, The Immense, in secret as in public, to be honest in your speech in satisfaction as in anger, to observe justice towards friends as towards enemies, to be moderate in wealth as in poverty."
Then, it is necessary to take refuge in ALLAH and to rely on Him when afflicted with trials and tribulations, and to attach the heart to ALLAH (The Glorified, The Exalted) as much as possible according to one's rank with ALLAH. One needs to adopt a respectful restraint towards ALLAH (The Glorified, The Exalted) such as defined in the word of the Prophet (peace and blessings be upon him) who said: "Have a true respectful restraint towards ALLAH". They said: "We have this respectful restraint, praise be to ALLAH". He said: "What you’re saying is not what I mean, for the respectful restraint is to preserve the head and what it contains, to safeguard the belly and what it gathers, to remind oneself of death and trials. One who longs for the hereafter forsakes the ornaments of this world; and whoever achieves all this, has a true respectful restraint towards ALLAH".
