This surah came after a short gap in revelation, when an opponent taunted the Prophet Muhammad that his Lord had abandoned him. It answers: your Lord has not left you, nor is He displeased. Then it tells him to care for orphans and those who ask for help, because he himself had once been an orphan in need.
Ad-Duha 93:1–11

93:1I swear by the forenoon,
وَٱلَّيْلِ إِذَا سَجَىٰ
93:2and by the night when it becomes peaceful,
مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَىٰ
93:3your Lord (O Prophet,) has neither forsaken you, nor has become displeased.
وَلَلْـَٔاخِرَةُ خَيْرٌ لَّكَ مِنَ ٱلْأُولَىٰ
93:4Surely the Hereafter is much better for you than the present life.
وَلَسَوْفَ يُعْطِيكَ رَبُّكَ فَتَرْضَىٰٓ
93:5And of course, your Lord will give you so much that you will be pleased.
أَلَمْ يَجِدْكَ يَتِيمًا فَـَٔاوَىٰ
93:6Did He not find you an orphan, and give you shelter?
وَوَجَدَكَ ضَآلًّا فَهَدَىٰ
93:7And He found you unaware of the way (the Sharī‘ah ), then He guided you.
وَوَجَدَكَ عَآئِلًا فَأَغْنَىٰ
93:8and He found you in need, then made you need-free.
فَأَمَّا ٱلْيَتِيمَ فَلَا تَقْهَرْ
93:9Therefore, as for orphan, do not oppress him,
وَأَمَّا ٱلسَّآئِلَ فَلَا تَنْهَرْ
93:10and as for the beggar, do not scold him.
وَأَمَّا بِنِعْمَةِ رَبِّكَ فَحَدِّثْ
93:11And about the bounty of your Lord, do talk.
