The Linen
Scholars have said that whoever sees themselves wearing a linen shirt might attain an honorable livelihood and lawful wealth. As for striped garments (al-burud), they may indicate goodness in both this world and the hereafter, especially the Hibrah type of burud. However, burud made of silk (ibrisim) might signify unlawful wealth.
