يَوۡمَ لَا يَنفَعُ ٱلظَّـٰلِمِينَ مَعۡذِرَتُهُمۡۖ وَلَهُمُ ٱللَّعۡنَةُ وَلَهُمۡ سُوٓءُ ٱلدَّارِ
The Day when their excuses will be of no profit to Zalimun (polytheists, wrong-doers and disbelievers in the Oneness of Allah). Theirs will be the curse, and theirs will be the evil abode (i.e. painful torment in Hell-fire).
وَلَقَدۡ ءَاتَيۡنَا مُوسَى ٱلۡهُدَىٰ وَأَوۡرَثۡنَا بَنِيٓ إِسۡرَـٰٓءِيلَ ٱلۡكِتَٰبَ
And, indeed We gave Musa (Moses) the guidance, and We caused the Children of Israel to inherit the Scripture [i.e. the Taurat (Torah)],
هُدٗى وَذِكۡرَىٰ لِأُوْلِي ٱلۡأَلۡبَٰبِ
A guide and a reminder for men of understanding.
فَٱصۡبِرۡ إِنَّ وَعۡدَ ٱللَّهِ حَقّٞ وَٱسۡتَغۡفِرۡ لِذَنۢبِكَ وَسَبِّحۡ بِحَمۡدِ رَبِّكَ بِٱلۡعَشِيِّ وَٱلۡإِبۡكَٰرِ
So be patient (O Muhammad SAW). Verily, the Promise of Allah is true, and ask forgiveness for your fault, and glorify the praises of your Lord in the Ashi (i.e. the time period after the midnoon till sunset) and in the Ibkar (i.e. the time period from early morning or sunrise till before midnoon) [it is said that, that means the five compulsory congregational Salat (prayers) or the 'Asr and Fajr prayers].
إِنَّ ٱلَّذِينَ يُجَٰدِلُونَ فِيٓ ءَايَٰتِ ٱللَّهِ بِغَيۡرِ سُلۡطَٰنٍ أَتَىٰهُمۡ إِن فِي صُدُورِهِمۡ إِلَّا كِبۡرٞ مَّا هُم بِبَٰلِغِيهِۚ فَٱسۡتَعِذۡ بِٱللَّهِۖ إِنَّهُۥ هُوَ ٱلسَّمِيعُ ٱلۡبَصِيرُ
Verily, those who dispute about the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, without any authority having come to them, there is nothing else in their breasts except pride [to accept you (Muhammad SAW) as a Messenger of Allah and to obey you]. They will never have it (i.e. Prophethood which Allah has bestowed upon you). So seek refuge in Allah (O Muhammad SAW from the arrogants). Verily, it is He Who is the All-Hearer, the All-Seer.
