Is it understood from the two stories that Imam Al-Hakim and Ibn Hibban believed in [seeking] intercession, or are they fabricated narrations?

Two stories have been narrated about the Hafiz Abu Ali al-Naysaburi and Ibn Hibban, indicating the fulfillment of needs through supplication at the graves of righteous people. However, these stories do not constitute a proof for the permissibility of innovated tawassul (seeking intercession) or the desirability of supplicating at graves, because proof in Islam is based solely on the Qur'an and Sunnah. Supplicating to Allah at graves is an innovation (bid'ah) and a means leading to shirk (polytheism). The success of a supplication sometimes may be a form of istidraj (gradual enticement towards ruin) and not an evidence of its legitimacy. Disputes must be referred back to the Qur'an and Sunnah. The mere mention of these stories by scholars does not imply their approval of them or their consideration as a legal proof.
