What you have described above is indeed one of the superstitious practices that we ought to reject.
There is no precedent for it in the practice of the Prophet (peace be upon him), his companions and pious predecessors (Salaf al-Salih).
We may do well to remember one of the basic principles of the shari’a: we are not allowed to institute rituals of worship based on our opinions or whims; rather we ought to wait for the sanction of the Law-Giver. The Prophet (peace be upon him) said, “Whoever innovates any practice without the sanction of ours in this religion, it ought to be rejected.”
It is a good practice to be encouraged as Imam Nawawi has stated in his acclaimed work al-Majmu’. He says it is recommended to gather people on a feast or food to express joy for the return of travelers (including those returning from Hajj or Umrah, etc.). It is one of the best ways of expressing gratitude and thanks to Allah for a safe return; it also strengthens the bonds of brotherhood and mutual love among Muslims and neighbors. We have precedent for this in the practice of the Prophet (peace be upon him). He used to sacrifice a camel, prepare a feast and invite the people to partake of it.
