Walking in Bazaar And Hot Desert (Istikhaara)

Asak

I did Istikhara for marriage and i saw myself in a big mall and just walking shopping by myself.
i then saw a clip where in the desert i have /own a piece of land or a stone and its very hot in the desert and difficult to own something. i see maybe a precious stone which is very hot and shines in the sun.
also i wan a tell u i made this isthikara in the evening say after4pm. is this still valid?
Jazakallaah
