By Allaah, it is weak (i.e. a weak hadeeth). The hadeeth about it is weak, and as long as it is weak we cannot say that it is something either recommended or obligatory, because of the fact that something being recommended is an Islamic ruling and an obligation is even a much greater (Islamic Ruling).
