There are many superstitions around us and people utter them because of arrogance. Is believing in those things Haram?
Assalamualaikum waramatullahi wabarakatuhu
We are not to believe in that because Allah the Exalted said in the Qur’an:
وما خلقتُ الجِنَّ والإنسَ إلا ليعبُدون
Ayahs 56, 57, 58 in Surat Adh-Dhariyat mean: Allah created the Jinn and Humans and ordered them to worship Him.
So everything including those superstition belong to Allah Azawajal, we just has to believe in Allah and always remember Allah as Allah said in Qur'an 13:28 that
"Those who believe (in the Oneness of Allah - Islamic Monotheism), and whose hearts find rest in the remembrance of Allah, Verily, in the remembrance of Allah do hearts find rest."
So we just have to remember Allah always and forget about those superstition
