Is adopting the view of the Malikis among Iraqis that سلس ( سلس البول: urinary incontinence; سلس الريح: continuous passing of gas; سلس الدم: continuous bleeding) does not nullify ablution at all, and that ablution is obligatory for each prayer—as held by the majority—considered correct, or is it merely following dispensations?

It is permissible to adopt the opinion given to you by some trustworthy scholars, and it is not obligatory to adhere to a specific madhhab. This opinion is closer to ease and removing hardship. However, the madhhab of the majority is more deserving due to the caution it embodies. Therefore, the correct approach is to follow the madhhab of the majority, as it is closer to piety and caution in religious matters.
