Encouragement to bear Difficulties, and the Command to Glorify your lord until comes to you certainty (i.e. death)
Allaah سُبحانه وتعالى said:
﴿وَلَقَدْ
نَعْلَمُ أَنَّكَ يَضِيقُ صَدْرُكَ بِمَا يَقُولُونَ - فَسَبِّحْ بِحَمْدِ رَبِّكَ
وَكُنْ مِّنَ السَّـجِدِينَ
(Indeed, We already
know that your breast is constrained by what they say. So glorify the praises
of your Lord and be of those who prostrate themselves (to Him).) meaning `We
know, O Muhammad, that you are distressed by their insults towards you, but do
not let that weaken your resolve or cause you to give up conveying the Message
of Allaah. Put your trust in Him, for He will suffice you and will support you
against them. Keep yourself busy with remembering Allaah, praising Him,
glorifying Him, and worshipping Him (which means Salah, or prayer)'
Hence Allaah سُبحانه وتعالى says:
﴿فَسَبِّحْ بِحَمْدِ رَبِّكَ وَكُنْ مِّنَ السَّـجِدِينَ ﴾
‘So glorify the
praises of your Lord and be of those who prostrate themselves (to Him’
Imâm Ahmad reported from Nu`aym bin Hammar
that he heard the Messenger of Allaah صلّى اللَّهُ
عليه وسلّم say:
«قَالَ اللهُ تَعَالَى يَا ابْنَ آدَمَ لَا تَعْجَزْ عَنْ
أَرْبَعِ رَكَعَاتٍ مِنْ أَوَّلِ النَّهَارِ أَكْفِكَ آخِرَه»
Allaah سُبحانه
وتعالى said,
"O son of
Adam! It is not too difficult for you to perform four Rak'at at the beginning
of the day, (and if you do them,) I will take care of you until the end of it.''
