And seek help in patience and As-Salât (the prayer) and truly it is extremely heavy and hard except for Al-Khâshi'ûn [i.e. the true believers in Allâh - those who obey Allâh with full submission, fear much from His Punishment, and believe in His Promise (Paradise, etc.) and in His Warnings (Hell, etc.)].(Al-Baqarah:45)
The Messenger ( صلى الله عليه و سلم ) said: Amazing is the affair of the believer, all his affairs are good. If he is encountered by joy he thanks and so it becomes good for him. If evil befalls him, then he becomes patient and that becomes good for him, and that isn't (the case) except with the believer.
Reported by Muslim through Suhaib ( رضي الله عنه ).
9. Supplicating with humility to Allaah
Allaah The Most High said:
وَقَالَ رَبُّكُمُ ادْعُونِي أَسْتَجِبْ لَكُمْ ۚ
إِنَّ الَّذِينَ يَسْتَكْبِرُونَ عَنْ عِبَادَتِي سَيَدْخُلُونَ جَهَنَّمَ دَاخِرِينَ
And your Lord said: "Invoke Me, [i.e. believe in My Oneness (Islâmic Monotheism)] (and ask Me for anything) I will respond to your (invocation). Verily! Those who scorn My worship [i.e. do not invoke Me, and do not believe in My Oneness, (Islâmic Monotheism)] they will surely enter Hell in humiliation!"
(Ghaafir:60)
And He said:
وَإِذَا سَأَلَكَ عِبَادِي عَنِّي فَإِنِّي قَرِيبٌ
أُجِيبُ دَعْوَةَ الدَّاعِ إِذَا دَعَانِ
فَلْيَسْتَجِيبُواْ لِي وَلْيُؤْمِنُواْ بِي لَعَلَّهُمْ يَرْشُدُونَ
And when My slaves ask you (O Muhammad صلّى اللَّهُ عليه وسلّم) concerning Me, then (answer them), I am indeed near (to them by My Knowledge). I respond to the invocations of the supplicant when he calls on Me (without any mediator or intercessor). So let them obey Me and believe in Me, so that they may be led aright.
(Al-Baqarah:186)
He The Most High said:
وَإِن يَمْسَسْكَ اللّهُ بِضُرٍّ فَلاَ كَاشِفَ لَهُ إِلاَّ هُوَ
وَإِن يَمْسَسْكَ بِخَيْرٍ فَهُوَ عَلَى كُلِّ شَيْءٍ قَدُيرٌ
And if Allâh touches you with harm, none can remove it but He, and if He touches you with good, then He is Able to do all things.
(Al-An’aam:17)
So upon you is supplication to Allaah-The Glorious and Most High and humbleness before him especially in the times of acceptance like the last third of the night, the last hour on the day of Jumu’ah, during prostration and other than that.
10. Distancing oneself from the magicians and sorcerers
The Messenger of Allaah ( صلى الله عليه و سلم ) said: Whoever goes to a fortune-teller then asks him a thing, forty day’s prayers won't be accepted, reported by Muslim. These are the ones who spread magic in the society, hence it is befitting to reprimand them, warn the people from them and to not believe them.
11. Dealing appropriately with others
Allaah The Most High said:
وَقُولُواْ لِلنَّاسِ حُسْناً وَأَقِيمُواْ الصَّلاَةَ وَآتُواْ الزَّكَاةَ
“and speak good to people [i.e. enjoin righteousness and forbid evil, and say the truth about Muhammad Peace be upon him ], and perform As-Salât(Iqâmat-as-Salât), and give Zakât.”
(Al-Baqarah:83)
Whether they maybe kin, companions, neighbors or other than them from the general people, good manners are a cause from the causes of having happiness. The most things that cause a person to enter paradise after Tawheed are good manners.
12. Avoiding disputes and arguments according to one’s ability
Because it is from the biggest causes of distress and if he’s afflicted with it then let him confront the bad with good, be patient, hide his anger and expect his reward with Allaah.
Allaah The Most High said regarding the attributes of the Pious:
الَّذِينَ يُنفِقُونَ فِي السَّرَّاء وَالضَّرَّاء وَالْكَاظِمِينَ الْغَيْظَ وَالْعَافِينَ عَنِ النَّاسِ وَاللّهُ يُحِبُّ الْمُحْسِنِينَ
Those who spend [in Allâh's Cause - deeds of charity, alms, etc.] in prosperity and in adversity, who repress anger, and who pardon men; verily, Allâh loves Al-Muhsinûn (the good*doers).
(Aal-‘Imraan:134)
