Stoning the জামারাত from the upper levels of the জামারাত complex is completely valid according to the consensus of contemporary scholars. The Saudi government built the multi-level জামারাত Bridge specifically to reduce the dangerous crowding that historically caused stampedes and deaths during the stoning ritual. The pillars (now basins) extend through all levels, and pebbles thrown from any level fall into the same collection basin.
Sheikh Ibn Baz explicitly endorsed stoning from the upper levels, stating that the pebbles reach the same Jamarah regardless of the level from which they are thrown. He noted that using the upper levels is not only permissible but may be preferable for those who would face danger from crowding on the lower levels, as preserving life is a fundamental Islamic principle. The Permanent Committee issued the same ruling.
Sheikh Ibn Uthaymeen confirmed that stoning from any level is equally valid and rewarded. He noted that the requirement is for the pebbles to hit the pillar or fall into the basin area — the height from which they are thrown is irrelevant to the validity of the act. He মুস্তাহাব that হাজীগণ choose the level with the least crowding to perform the stoning safely and with focus. Al-Fawzan added that the multi-level structure is a modern ijtihad (scholarly effort) to protect হাজীগণ, and scholars unanimously support its use.
