I just prayed Jumu'ah and the Imam recited الضالين and correctly elongated the "Alif" but because maybe he ran out of breath he didn't recite the shaddah on "ل". There wasn't a long pause at all and he finished reciting the ayah. This happened before in another Jumu'ah are these salah valid?

Ustadh AbdulAziz al-Haqqan
Valid
