5 things i must do if i love ALLAH

1) always remember Him

¨فَٱذْكُرُونِىٓ أَذْكُرْكُمْ
¨" Remember Me, I will remember you.. "
(Quran 2:152).

2)have positive thinking about Him.

¨ It is narrated in a hadith Qudsi "God Most High says I am as my Servant - think I am. I am with him when he makes mention of Me. If he makes mention of Me by himself, I make mention of him to Myself. If he makes mention of Me in an assembly, I make mention of him in an assembly better than his. If he comes closer to Me a hand span, I come closer to him arms-length, if he comes to Me walking, I come to him running."

3) love the things that Allah love.
 قُلْ إِن كُنتُمْ تُحِبُّونَ اللّهَ فَاتَّبِعُونِي يُحْبِبْكُمُ اللّهُ وَيَغْفِرْ لَكُمْ ذُنُوبَكُمْ وَاللّهُ غَفُورٌ رَّحِيمٌ
 Say (O Muhammad SAW to mankind): "If you (really) love Allah then follow me (i.e. accept Islamic Monotheism, follow the Qur'an and the Sunnah), Allah will love you and forgive you of your sins. And Allah is Oft-Forgiving, Most Merciful." (ali-imran :31)

4)hate the things that Allah hates.

اقْتَرَبَ لِلنَّاسِ حِسَابُهُمْ وَهُمْ فِي غَفْلَةٍ مُعْرِضُونَ 
(21:1) The time of the reckoning of the people has drawn near, *1 and yet they are turning away (from the Admonition) in heedlessness.
5) do not love world excessively.

And this worldly life is not but diversion and amusement. And indeed, the home of the Hereafter - that is the [eternal] life, if only they knew.(Al-Ankabut:64)
last but not least,
  مَنْ أَحَبَّ لِقَاءَ اللهِ أَحَبَّ اللهُ لِقَاءَهُ
