Praise be to Allah.
I do not know anything about that, although picking it up with the right hand is better. The right hand is preferable in all cases and the Prophet (blessings and peace of Allah be upon him) used to start on the right when purifying himself and combing his hair, and he used to use his right hand to take and give, and to shake hands and so on, and he used the left hand for everything else. If there is a need to pick up the Mushaf with the left hand because the right hand is incapacitated and so on, there is nothing wrong with that in sha Allaah, because both hands work together, and there is no intention when picking up the Mushaf with the left hand to show disrespect or carelessness. Rather it is cooperation of one hand with the other, and the two work together. If he holds it in the left hand and reads or in the right hand and reads, there is nothing wrong with it in either case, in sha Allah, but holding it in the right hand is preferable and is better, because of what we have mentioned above about the right hand being preferred in taking, giving, eating and so on.
