The outgoing chairman of the Islamic conference, Pakistani President Mohammed Zia ul-Haq, presented a largely pessimistic report yesterday to 38 Moslem leaders here, saying little progress had been made in the group's efforts to resolve the Iranian-Iraqi war and the Afghanistan crisis.

Zia said he had done "all that was possible" to arrange for an end to the hostilities, including his visit as the head of an Islamic negotiating team to the warring countries, Washington correspondent David Ottaway reported.

On Afghanistan, Zia said efforts by both the Islamic conference and the United Nations to arrange for the withdrawal of Soviet troops and political negotiations had "not made much headway."

There has been concern in Western circles that Zia might be weakening on Afghanistan and might be willing for separate talks between the Afghan government and the governments of Pakistan and Iran, which the Soviet Union hopes to use to gain recognition for the Kabul government.

But today Zia told the conference "no compromise" would be acceptable to the principles he has spelled out calling for the "immediate, unconditional and total withdrawal of Soviet forces" from Afghanistan in recognition of the right of the Afghan people to choose their own government "free from external influence."

Tonight, Saudi Arabian King Khalid rejected placing Jerusalem under an international authority and called on Christians to join Moslems in the "liberation of the holy places" from Israeli control.
