What is the ruling on the Hajj of one who possesses investment certificates, but whose funds for Hajj are from another source?

If someone performs Hajj with money earned from lawful means, then their Hajj is valid. The validity of the Hajj is not affected by the pilgrim having another source of income that is unlawful. The majority of scholars hold the view that Hajj performed with unlawful money is valid, but the one who performs it incurs sin. Their evidence for this is that Hajj consists of specific acts of worship, and the prohibition is due to a meaning external to these acts themselves. It should be known that investment certificates are of various types, some of which are prohibited and some permissible.
