Hello, MaLina. In the Arabic-Arabic Dictionary we find: أحبَّ يُحِبّ ، أَحْبِبْ / أَحِبَّ ، إحبابًا So the second is correct, also you can say: أَحْبِبْ نفسك أولًا In addition, we find also: حبَّ حَبَبْتُ ، يَحِبّ ، احْبِبْ / حِبّ ، حُبًّا ، فهو حَابّ ، والمفعول مَحْبوب وحَبِيب حبَّ الإنسانُ والشيءُ : صَار محبوبًا حبَّ فلانًا : ودّه حَبَبْتُ أَنْ أُبَلِّغَكَ سَلامِي : رَغِبْتُ ، وَدِدْتُ حَبَّ فَتاةً : أَحَبَّها ، عَشِقَها ، رَغِبَ فيها Which implies that, the first one is correct too. :) http://www.almaany.com/ar/dict/ar-ar/home.php?word=%D8%A3%D8%AD%D8%A8⟨_name=ar-ar&type;_word=0&dspl;=0

Olá, ‍The correct sentence is the second one, which means "Love yourself first". The other two sentences are incorrect.

أحب نفسك أولا
