يَا أَيُّهَا النَّاسُ اعْبُدُوا رَبَّكُمْ
يَا أَيُّهَا النَّاسُ O People
When I was reading through the Madina Book 2 I came across some of the rules of using
يَا and I vaguely remember scribbling down some notes which said when
يَا is used with a noun that starts with
ال then
أَيُّهَا is inserted in the sentence to give, in this case
يَا أَيُّهَا النَّاسُ as opposed to
يَا النَّاسُ This brought to mind when we read in the salah the Atahiyyat in the prayer when we say
السلام عليك أَيُّهَا النبي ورحمة لله و بركاة
In essence, we are saying ‘May peace be upon you O Prophet…’ and some may say the more correct way to read the Atahiyyat now is to say
السلام على النبي
'May peace be upon the Prophet'
In one narration the Sahbah quoted saying the former whilst the Prophet (saw) was alive and among them and switched to the latter after his (saw’s) death.
I just found that interesting when I thought about the Attahiyat, a digression non the less...
Moving on...
اعْبُدُوا Worship (m3+)
رَبَّكُمْ Your Lord
يَا أَيُّهَا النَّاسُ اعْبُدُوا رَبَّكُمْ
O [You] People, worship your Lord
