Tehran, July 31, IRNA -- Tehran interim Friday Prayers Leader Ayatollah Seyyed Ahmad Khatami appreciated Iran's President Hassad Rouhani and nuclear negotiating team for their efforts in the marathon talks with world powers.

Addressing worshippers on Friday, he said that the negotiating team entered the scene with good intentions and pursued a marathon job.

Ayatollah Khatami also described negotiators as fighters of the diplomacy front.

Referring to stances of Supreme Leader Ayatollah Seyyed Ali Khamenei in the field, he said the Leader has underlined that text of the agreement should be examined carefully.

'This is a major issue and we should wait until it takes its legal course,' Friday prayers leader said, noting that the nuclear issue is not a factional one; rather it is a national problem pertaining to all.

Ayatollah Khatami also said nobody should make factional advantage of the issue because it will not produce desirable results.

All should strive for success of nuclear issue, he said.

Underlining fairness in evaluation of the deal, he said there is no reason for being unfair towards the deal and one should see strong and weak points together and tell the strong points in a friendly manner and warn about its weak points.

The atmosphere for constructive criticism should be prepared, the cleric said, noting that critical attitude towards the issue may further enlighten the way.

'If we call all criticisms as destruction, then the elites will go away,' he said, calling on critics to offer constructive views on the issue.
