Allah, the Exalted, informs about His believing servants, who work righteous deeds -- deeds that He is pleased with because they are in accordance with the legislation of Muhammad -- that He plants love for them in the hearts of His righteous servants. This is something that is absolutely necessary and there is no avoiding it. This has been reported in authentic Hadiths of the Messenger of Allah in various different ways. Imam Ahmad recorded that Abu Hurayrah said that the Prophet said,

«إِنَّ اللهَ إِذَا أَحَبَّ عَبْدًا دَعَا جِبْرِيلَ، فَقَالَ: يَا جِبْرِيلُ، إِنِّي أُحِبُّ فُلَانًا فَأَحِبَّهُ قَالَ: فَيُحِبُّهُ جِبْرِيلُ، قَالَ: ثُمَّ يُنَادِي فِي أَهْلِ السَّمَاءِ: إِنَّ اللهَ يُحِبُّ فُلَانًا فَأَحِبُّوهُ، قَالَ: فَيُحِبُّهُ أَهْلُ السَّمَاءِ، ثُمَّ يُوضَعُ لَهُ الْقَبُولُ فِي الْأَرْضِ، وَإِنَّ اللهَ إِذَا أَبْغَضَ عَبْدًا دَعَا جِبْرِيلَ فَقَالَ: يَا جِبْرِيلُ إِنِّي أُبْغِضُ فُلَانًا فَأَبْغِضْهُ، قَالَ: فَيُبْغِضُهُ جِبْرِيلُ، ثُمَّ يُنَادِي فِي أَهْلِ السَّمَاءِ: إِنَّ اللهَ يُبْغِضُ فُلَانًا فَأَبْغِضُوهُ، قَالَ: فَيُبْغِضُهُ أَهْلُ السَّمَاءِ، ثُمَّ يُوضَعُ لَهُ الْبَغْضَاءُ فِي الْأَرْض»

(Verily, whenever Allah loves a servant of His, He calls Jibril and says, "O Jibril, verily I love so-and-so, so love him.'' Thus, Jibril will love him. Then, he (Jibril) will call out to the dwellers of the heavens, "Verily, Allah loves so-and-so, so you too must love him.'' Then the dwellers of the heavens love him and he will be given acceptance in the earth. Whenever Allah hates a servant of His, He calls Jibril and says, "O Jibril, verily I hate so-and-so, so hate him.'' Thus, Jibril will hate him. Then, he (Jibril) will call out amongst the dwellers of the heavens, "Verily, Allah hates so-and-so, so you too must hate him.'' Then the dwellers of the heavens hate him and hatred for him will be placed in the earth.) Al-Bukhari and Muslim reported narrations similar to this. Ibn Abi Hatim recorded that Abu Hurayrah said that the Prophet said,

«إِذَا أَحَبَّ اللهُ عَبْدًا نَادَى جِبْرِيلَ: إِنِّي قَدْ أَحْبَبْتُ فُلَانًا فَأَحِبَّهُ، فَيُنَادِي فِي السَّمَاءِ، ثُمَّ يُنْزِلُ لَهُ الْمَحَبَّةَ فِي أَهْلِ الْأَرْضِ، فَذَلِكَ قَوْلُ اللهِ عَزَّ وَجَلَّ:

﴿إِنَّ الَّذِينَ ءَامَنُواْ وَعَمِلُواْ الصَّـلِحَاتِ سَيَجْعَلُ لَهُمُ الرَّحْمَـنُ وُدّاً ﴾

(Whenever Allah loves a servant of His, He calls Jibril (saying), "Verily, I love so-and-so, so love him.'' Then, Jibril calls out into the heavens and love for him descends among the people of the earth. That is the meaning of the statement of Allah, the Mighty and Sublime: (Verily, those who believe and work deeds of righteousness, the Most Gracious will bestow love for them.)) ﴿19:96﴾ This was also reported by Muslim and At-Tirmidhi and At-Tirmidhi said, "Hasan Sahih.''
