السلام عليكم ورحمة الله وبركاته احسن الله اليك ووفقك الله Is it allowed, disliked, or preferred, to change the riwayah you read in in the Salah? For example, reading the fatihah in Qalun and then ikhlas in khalaf an hamza. Or your first rakah is a different riwayah to your second? جزاك الله خيرا

Ustadh AbdulAziz al-Haqqan
I wouldn't do so. You will confuse the people as well.
