Theres a big difference between the two. You are correct, Istighathah is what is considered shirk. However, some wrongly refer to Istighathah as Tawassul. Brother TripoliSunni and "Hussains" post are pretty accurate. As for the prophet peace be upon him being alive, or martyrs who are alive (with their Lord, as the Qur'aan says) this is usually used as an arguement to go to the prophet at his grave and ask him for help, in a way no companion ever did. This then extends to Jilani, Hussain, Haqqani etc and never ends. Qur'aan says "And they worship besides Allah things that hurt them not, nor profit them, and they say: "These are our intercessors with Allah." Say: "Do you inform Allah of that which He knows not in the heavens and on the earth?" Glorified and Exalted be He above all that which they associate as partners with Him!" So they didnt really say that they are Allah, but they just considered them intercessors. Also `And those who take Awliya (note the word used here is Awliya) beside Him (Say):'We worship them only that they may bring us near to Allah (swt). Verily Allah (swt) will judge between them concerning that wherein they differ. Truly, Allah (swt) guides not Him who is a Liar and a disbeliever.' (Qur'an 39:4) "To proceed, if anyone amongst you used to worship Muhammad, then Muhammad has passed away, but if (anyone of) you used to worship Allah, then Allah is Alive and shall never die. Allah said, "And Muhammad is but a messenger; the messengers have come before him; if then he dies or is killed will you turn back upon your heels? And whoever turns back upon his heels, he will by no means do harm to Allah in the least and Allah will reward the grateful." (3.144) 'Umar said, "By Allah, when I heard Abu Bakr reciting it, my legs could not support me and I fell down at the very moment of hearing him reciting it, declaring that the Prophet had passed away."[ This was the position of the companions, as they didnt remain in denial, saying no hes alive, and twist verses to make it permissable to go to his grave and ask for help etc. Allah is closer to us. “And when My servants ask you concerning Me, then surely I am very near; I answer the prayer of the suppliant when he calls on Me, so they should answer My call and believe in Me that they may walk in the right way
