Quran 42:23: Commands us to love the AhlulBayt.
Quran: Ash-Shuraa (42:23)
Translation: Shakir

That is of which Allah gives the good news to His servants, (to) those who believe and do good deeds. Say: I do not ask of you any reward for it but love for my near relatives; and whoever earns good, We give him more of good therein; surely Allah is Forgiving, Grateful.

 
Translation: Yusuf Ali

That is (the Bounty) whereof Allah gives Glad Tidings to His Servants who believe and do righteous deeds. Say: "No reward do I ask of you for this except the love of those near of kin." And if any one earns any good, We shall give him an increase of good in respect thereof: for Allah is Oft-Forgiving, Most Ready to appreciate (service).

 
Translation: Qaribullah & Darwish

This is the glad tidings that Allah gives to His worshipers, who believe and do good works. Say: 'For this I ask of you no wage except the love of the (Prophet's) relatives. We will add good to whosoever gains a good deed. Allah is the Forgiving and the Thanker'

 
Translation: Sarwar

This is the glad news which God gives to His servants, the righteously striving believers. (Muhammad), say, "I do not ask you for any payment for my preaching to you except (your) love of (my near) relatives." Whoever achieves virtue will have its merit increased. God is All-forgiving and Appreciating.

 
Translation: Qarai

Such is the good news that Allah gives to His servants who have faith and do righteous deeds! Say, ‘I do not ask you any reward for it except the love of [my] relatives.’ Whoever performs a good deed, We shall enhance its goodness for him. Indeed Allah is all-forgiving, all-appreciative.

ذَلِكَ ٱلَّذِى يُبَشِّرُ ٱللَّهُ عِبَادَهُ ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّلِحَتِ ۗ قُل لَّآ أَسْـَٔلُكُمْ عَلَيْهِ أَجْرًا إِلَّا ٱلْمَوَدَّةَ فِى ٱلْقُرْبَىٰ ۗ وَمَن يَقْتَرِفْ حَسَنَةًۭ نَّزِدْ لَهُۥ فِيهَا حُسْنًا ۚ إِنَّ ٱللَّهَ غَفُورٌۭ شَكُورٌ ‎

Rasulullah (ﷺ): Love Allah for what He nourishes you with of His Blessings, love me due to the love of Allah, and love the Ahlul-Bayt due to love of me.
Jami` at-Tirmidhi Book 49, Hadith 188
Narrated Ibn 'Abbas:

that the Messenger of Allah (ﷺ) said: "Love Allah for what He nourishes you with of His Blessings, love me due to the love of Allah, and love the Ahlul-Bayt (people of my house) due to love of me."

حَدَّثَنَا أَبُو دَاوُدَ، سُلَيْمَانُ بْنُ الأَشْعَثِ قَالَ أَخْبَرَنَا يَحْيَى بْنُ مَعِينٍ، قَالَ حَدَّثَنَا هِشَامُ بْنُ يُوسُفَ، عَنْ عَبْدِ اللَّهِ بْنِ سُلَيْمَانَ النَّوْفَلِيِّ، عَنْ مُحَمَّدِ بْنِ عَلِيِّ بْنِ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ أَحِبُّوا اللَّهَ لِمَا يَغْذُوكُمْ مِنْ نِعَمِهِ وَأَحِبُّونِي بِحُبِّ اللَّهِ وَأَحِبُّوا أَهْلَ بَيْتِي لِحُبِّي ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ إِنَّمَا نَعْرِفُهُ مِنْ هَذَا الْوَجْهِ ‏.
