King Abdullah of Saudi Arabia congratulated Hassan Rowhani on winning Iran's presidential election, praising what he described as Mr Rowhani's wish to improve relations between the two countries.
Ties between have been tense over many issues, notably the war in Syria, where they back rival combatants, political unrest in Bahrain, and a dispute over Iran's pursuit of nuclear power.
The Saudi Press Agency reported late on Sunday that the king had sent a cable of congratulations wishing Mr Rowhani "permanent good health and happiness and the people of Iran steady progress and prosperity".
Abdul Jabar Qahraman was meeting supporters in his campaign office in the southern Afghan province of Helmand when a bomb hidden under a sofa exploded on Wednesday.
The blast in the provincial capital Lashkar Gah killed the Afghan election candidate and at least another three people, Interior Minister Wais Ahmad Barmak told reporters. Another three were wounded, while three suspects were detained, he said.
The Taliban – which controls much of Helmand and has vowed to disrupt the October 20 parliamentary elections – claimed responsibility for the attack.
Mr Qahraman was at least the 10th candidate killed so far during the campaign season, and the second from Lashkar Gah this month. Another candidate, Saleh Mohammad Asikzai, was among eight people killed in a suicide attack last week. Most of the slain candidates were murdered in targeted assassinations, including Avtar Singh Khalsa, the first Afghan Sikh to run for the lower house of the parliament.
The same week the Taliban warned candidates to withdraw from the elections. On Wednesday the group issued fresh warnings, calling on educational workers to stop schools from being used as polling centres.

It's Monty Python's Crashing Rocket Circus
To the theme tune of the famous zany British comedy TV show, SpaceX has shown exactly what can go wrong when you try to land a rocket.
The two minute video posted on YouTube is a compilation of crashes and explosion as the company, created by billionaire Elon Musk, refined the technique of reusable space flight.
SpaceX is able to land its rockets on land once they have completed the first stage of their mission, and is able to resuse them multiple times - a first for space flight.
But as the video, How Not to Land an Orbital Rocket Booster, demonstrates, it was a case if you fail, try and try again.
