Believing in superstitions

In Pre-Islamic world, the people were superstitious. They would wait for years together for a so-called auspicious moment to start a new venture, they would commence a journey on a particular day and so on. Allah the most gracious took pity on the humankind. The most revered Prophet (SAW) came to rid people of superstitions, to teach them Allah alone was the creator and the sustainer. The Holy Prophet (SAW) told them no day, no moment was cursed. Even a leaf cannot move without the permission of Allah the almighty. The message was conveyed in clear terms. Slowly the people started believing in oneness of Allah the most exalted and the Prophethood of Muhammad (SAW). And, there was no scope for superstitions in the society that emerged. Muslims would start a new venture on any day, any moment, they stopped looking for `auspicious’ moments to solemnize marriages. They believed in the one and the only Allah.
Great people like Mir Syed Ali Hamdani (RA) took great pains to enlighten Kashmiris. A major chunk of the population embraced Islam and took pledge to worship the one and the only Master, they decided to shun the age old traditions which had elevated a handful of people to the level of God. These `priveleged’ persons used to exploit people for their petty interests; they would open their huge books to decide who had to do what and when. They would decide when marriage of a person must take place, they would decide (for the people) where they must construct a shop or run their business. In short, the commoner had no say in the affairs of his own life. The people had deliberately and willingly surrendered their freedom to these exploiters.
In the contemporary Kashmir where markets are flooded with Islamic literature, where Darul Alooms have been set up everywhere, where every person knows the basics of Islam, the people still seem to cling to the traditions of Pre-Shah-e-Hamdan (RA) period. A large chunk of Kashmiris still do not solemnize a marriage on Tuesdays and Saturdays. They do not start a new venture on 3rd, 13th and 23rd day of a month saying these dates were not auspicious. Like their non-Muslim ancestors, they still hire a person who looks for auspicious days and moments for them. This is totally against the teachings and spirit of Islam. A Muslim has to believe in Oneness of Allah, Prophethood of Muhammad (SAW), Prophethood of all the Prophets (AS), Angels, books revealed to Prophets (AS), the day of judgement. A Muslim must have firm faith that nobody other than Allah can do him any wrong and nobody other than Allah the most Merciful can do him any good. This is the foundation and one who fears that a particular day, a particular moment can bring him calamity or disaster does not actually believe in Allah the almighty. He must go for self introspection before it is too late. These are basically Hindu customs and unfortunately after more than six hundred years, the Kashmiri Muslims find it difficult to relieve themselves of these vices.
Nowhere does the Holy Quran mention that a particular day is cursed, nowhere do the hadith books mention that a particular moment is auspicious, the most revered Prophet (SAW) did not fix a particular time for marriages, the Calpihs (RA) did not do it either. So why should Muslims do it now?
