Lessons from Sūrah 20 - Sūrat Ṭāhā
Make this du‘ā regularly:
رَبِّ اشْرَحْ لِي صَدْرِي وَيَسِّرْ لِي أَمْرِي وَاحْلُلْ عُقْدَةً مِنْ لِسَانِي يَفْقَهُوا قَوْلِي
'O Allāh put my heart at peace for me, make my task easy for me, and untangle the knot from my tongue so that they may understand my speech.’
When carrying out the command of Allāh, don’t fear anything, and remember that Allāh is with you.
Allāh neither makes mistakes nor forgets.
Allāh is forgiving for those who repent, believe in Him and do good.
Allāh’s Knowledge encompasses everything.
On the Day of Judgement, the ground will be completely flat.
There shall be complete silence in the presence of Allāh on the Day of Judgement.
The only intercession on that Day will be for those whom Allāh grants permission.
There will be no injustice whatsoever on that Day.
Make the following du‘ā regularly:
رَبِّ زِدْنِي عِلْمًا
'O Allāh increase me in knowledge.’
Whoever turns away from the remembrance of Allāh will lead a straitened life, and will be raised on the Day of Judgement in a bad state.
Allāh has granted wealth to the disbelievers to test them. Whatever little Allāh has granted us in comparison, is better for us, though we may not understand it.
Instruct your family members to establish ṣalāh and be punctual in it.
 قَالَ لَا تَخَافَآ ۖ إِنَّنِى مَعَكُمَآ أَسۡمَعُ وَأَرَىٰ (٢٠: ٤٦)
 وَإِنِّى لَغَفَّارٌ لِّمَن تَابَ وَءَامَنَ وَعَمِلَ صَـٰلِحًا ثُمَّ ٱهۡتَدَىٰ (٢٠: ٨٢)
