Issue 6: It is not allowed to act upon the verdict of a deceased Jurist in the beginning (of Taqleed), although he be the most learned, based on obligatory precaution. Issue 7: It is obligatory for the one obliged to observe the Islamic law (Mukallaf) that he learn the matters which he has need of, or those matters which customarily occurs for him or that he learns the method of precaution (in those matters).
Issue 8: When people perform their acts without following (a Jurist) for a period of time, then, follow a Jurist. Then, if their previous acts are in agreement with the verdicts of this Jurist, the acts are correct. Otherwise, they are obligated to repeat those acts. Likewise is it when they had followed a Jurist without sufficient verification. Issue 9: When the verdict of a Jurist has changed, it is obligatory to act according to the new verdict.
However, the acts which were performed according to the previous verdict are correct and there is no need of repetition. Thus it is when one switches from one Jurist to another. It is not necessary to repeat the previous acts when they differ from the new opinions. Issue 10: When two Jurists are equal, the follower is able to choose between them and it is allowed to follow one of the two in some matters and follow the other in other matters.
Issue 11: Water is either Pure [Mutlaq] or Mixed [Mudhaaf]. Mixed water is that which is not possible to apply the term water to alone. For example, it is said to be juice, soapy water, rose water. Regarding pure water, it is that which it is possible to apply the term water to without restriction or condition, like common water. Issue 12: Pure water has some types and each type has specific rulings.
These types are: • Large quantity of water [Kurr Water] • Small quantity of water [Qaleel Water] • Flowing water and the water of pipes [Jaari Water] • Rain water [Ghayth/Matar Water] • Well water [Bi’r Water] All of these waters have in common that they are pure [Taahir] and purifiers [Mutahhir]. Mixed water, however, does not purify anything. Rather, it becomes impure [Najis] upon contact with impurities [Najaasah].
Issue 13: Kurr water is water which, if poured into a container, each of its length, width and depth is three and a half spans of the hand in order to fill a container or that water whose weight is 384 Kilograms or 384 Liters (based on obligatory precaution). The standard in the span of the hand is the medium hand span.
