“Say, [O Muhammad عليه الصلاة و السلام], if you (really) love Allaah then follow me.
Allaah will love you and forgive you of your sins. And Allaah is Oft-Forgiving, Most Merciful.” [Soorah Aali ‘Imraan, 3:31]
Ibn-Kathir (r.a) said in his Tafsir: “Allah ta’ala’s love is attained by following the Messenger sallallaahu ‘alayhi wasallam. This honourable Ayah judges against those who claim to love Allah yet do not follow the way of Mohammad sallallaahu ‘alayhi wasallam and his religion in all his statements, actions and conditions.” Tafsir 2/145
Abu Huraira (may Allah be pleased with him) narrated that Allah’s Messenger (peace and blessings of Allah be upon him) said that Allah said:
“I will declare war against him who shows hostility to a pious worshipper of mine. And the most beloved things with which My slave comes nearer to Me, is what I have enjoined upon him; and My worshipper keeps on coming close to Me through performing Nawafil (praying or doing extra deeds besides what is obligatory) till I love him, then I become his sense of hearing with which he hears, and his sense of sight with which he sees, and his hands with which he grips, and his legs with which he walks; and if he asks Me, I will give him, and if he asks My protection (refuge), I will protect him.” [Al-Bukhari].
“The greatest reward comes from the greatest trial. When Allah loves people, He tests them, and whoever accepts it gains the pleasure of Allah and whoever complains earns His wrath.” [Tirmidhi]
Loving, Visiting & Helping one another for His sake
“My love is guaranteed for two who love one another for My sake; My love is guaranteed for two who visit one another for My sake; My love is guaranteed for two who help one another for My sake; My love is guaranteed to for two who uphold ties with one another for My sake.” [Ahmad]
