Issue: Do the two evidences cancel one another out if one of them is dated, or if both are dated? Yes—if both are dated and we know that the date of one is later than that of the other, judgment is given according to the later-dated one. The ruling that they cancel one another out applies when their contradiction is absolute in every respect.
His statement: “Delivering it is an individual obligation upon the one who has undertaken it”—but this is subject to conditions. He said:
His statement: “When he is summoned to it”: this is the first condition: that he be summoned to deliver it. If he is not summoned, delivering it is not binding upon him. But if he delivers it without having been summoned, is this praiseworthy or blameworthy?
The scholars differed over this. Some held that it is blameworthy, citing the Prophet’s ﷺ statement: “The best of people are my generation, then those who come after them, then those who come after them. Then there will come people who give testimony without being asked to do so.” (1) In another narration: “They give testimony before being asked to do so.” (2) They said that this condemns one who gives testimony before being asked for it. They also reasoned that a person who hastens to give testimony before being asked may become the object of suspicion: it may be thought that he is biased in favor of the person for whom testimony is given, or against the person against whom it is given. Otherwise, what caused him to testify before his testimony was requested?!
Some scholars said instead that it is preferable for him to testify, even if he has not been asked to do so.
