Sunnah is more important to you than your forefathers' cultures, custom.

We live in an age where there is no land with sharia laws fully implemented currently, instead we have come across many strange cultures, that we are taught to follow instead of the beautiful sunnah of Prophet peace be upon him.

We often claim that we love Prophet peace be upon him, but we do not know what the love means. It is not the natural feeling that man gets toward his parents, children, and so. This means the obedience which we try to follow his footstep.

We come across many cultures that ends up being shirk, such as seeking help from dead, wearing amulet.

And then we come across some cultures that goes against Quran and Sunnah, such as some people shaving their beard and keeping moustache, or some keep beard but only trimmed because they see it more handsome than long beard.

Without following the Sunnah, how can we claim that we truly love Prophet peace be upon him? How can we even say that we love Allah when He commands us to follow Prophet peace be upon him yet we disobey Him??

Allah says in Quran.

Aal-e-Imran 3:31

قُلْ إِن كُنتُمْ تُحِبُّونَ ٱللَّهَ فَٱتَّبِعُونِى يُحْبِبْكُمُ ٱللَّهُ وَيَغْفِرْ لَكُمْ ذُنُوبَكُمْۗ وَٱللَّهُ غَفُورٌ رَّحِيمٌ

Say, [O Muhammad], "If you should love Allah, then follow me, [so] Allah will love you and forgive you your sins. And Allah is Forgiving and Merciful."

An-Nisa' 4:80

مَّن يُطِعِ ٱلرَّسُولَ فَقَدْ أَطَاعَ ٱللَّهَۖ وَمَن تَوَلَّىٰ فَمَآ أَرْسَلْنَٰكَ عَلَيْهِمْ حَفِيظًا

He who obeys the Messenger has obeyed Allah ; but those who turn away - We have not sent you over them as guardian

Do not follow your forefathers blindly.

Al-Baqarah 2:170

وَإِذَا قِيلَ لَهُمُ ٱتَّبِعُوا۟ مَآ أَنزَلَ ٱللَّهُ قَالُوا۟ بَلْ نَتَّبِعُ مَآ أَلْفَيْنَا عَلَيْهِ ءَابَآءَنَآۗ أَوَلَوْ كَانَ ءَابَآؤُهُمْ لَا يَعْقِلُونَ شَيْـًٔا وَلَا يَهْتَدُونَ

And when it is said to them, "Follow what Allah has revealed," they say, "Rather, we will follow that which we found our fathers doing." Even though their fathers understood nothing, nor were they guided?
