Security guards, in Madinah are VERY strict about people reciting the "salam" and surah-fatiha for the Prophet (pbuh) anyone praying in the Prophet's (pbuh's) direction.. or standing too long is asked to leave..
What is meant by tawassul and waseelah is four things:
the kind of tawassul without which faith cannot be complete, which is seeking to reach Allaah (tawassul) by believing in Him and His Messengers, and obeying Him and His Messenger, This is what is meant in the aayah (interpretation of the meaning):
“O you who believe! Do your duty to Allaah and fear Him. Seek the means of approach to Him…”
[al-Maa’idah 5:35]
This includes seeking to approach Allaah through His Names and Attributes, or by doing acts of obedience and worship by which one seeks to approach Allaah, and so on.
Seeking to approach Allaah by asking His Messenger (peace and blessings of Allaah be upon him) to make du’a’ for one during his lifetime, and the believers asking one another to make du’aa’ for one another. This follows on from the first type and is encouraged.
Seeking to approach Allaah by virtue of the status and virtues of some created being, such as saying, “O Allaah, I ask You by virtue of Your Prophet” and so on. This is allowed by some of the ‘ulama’, but this opinion is da’eef (weak). The correct view is that it is definitely haraam, because there can be no tawassul in du’aa’ except by virtue of the Names and Attributes of Allaah.
Tawassul as it is understood by many of the Muslims of later times, which is calling on the Prophet (peace and blessings of Allaah be upon him) and seeking his help (or seeking the help of the dead and so-called awliya’). This is a form of major shirk, because calling on or seeking help from anyone other than Allaah with regard to something that that only Allaah is able to do is a kind of worship, and directing worship to anyone or anything other than Allaah is major shirk.
Allaah says (interpretation of the meaning): “ And whoever invokes (or worships) besides Allaah, any other god, of whom he has no proof, then his reckoning is only with his Lord. Surely, al-kaafiroon (the disbelievers in Allaah and in the Oneness of Allaah) will not be successful.” [al-Mu’minoon 23:117].
Allaah states that anyone who calls on anything other than him is taking that thing as a god, as He says (interpretation of the meaning): “…And those, whom you invoke or call upon instead of Him, own not even a qitmeer (the thin membrane over a date-stone). If you invoke (or call upon) them, they hear not your call, and if (in case) they were to hear, they could not grant it (your request) to you. And on the Day of Resurrection, they will disown your worshipping them. And none can inform you (O Muhammad), like Him Who is the All-Knower (of everything).” [Faatir 35:13-14].
