How you react upon disagreement?

Where should I start first ek? Today, I had spent my time reading the magazine named SOLUSI. Lama sungguh rasanya tak baca. This time the main topic entitled " Syurga itu Benar". I read during a programmed I attended this morning. Because I am not really interested in that program, then I decided to spend with my SOLUSI.

During that programme, I personally disagree with the speaker's speech. It was more like a talk actually. But,I just kept my mouth shut and continue reading. Mengutuk didalam hati saja.huhu. Then, when I keep reading it, I found one hadith that really match with my situation right now.

Rasulullah pernah bersabda yang bermaksud : "Sesiapa yang percaya kepada Allah dan hari akhirat hendaklah dia berkata baik ataupun diam."

Masya Allah, Rasulullah had left us with so many advice and guidance, but sometimes we just ignore it, and maybe hesitant to follow it.  During the programme, the reason why I just keep quiet is I remember when I  watch this dai' in the youtube, he had mentioned about one of our scholar (if I'm not mistaken,sorry I have short term memory). He do not agree with another scholar's opinion and what he do? He did not trying to debate or criticize  the other scholar, but he just keep quiet.

We live in a world with other people that absolutely has their own perspective, opinion. Accept the difference and react appropriately. We may disagree with our friend opinion, but how to react? Rasulullah had teach us, Allah had mentioned in the Quran. Let makes Islam as our way of life. the only way.
